This AR-15/M16-A1 forged lower receiver are the ideal choice for those looking for reproduction build of a Vietnam-era type rifle because most forged lowers produced today feature incorrect "A2" profiles. [17], In January 1963, Secretary of Defense Robert McNamara concluded that the AR-15 was the superior weapon system and ordered a halt to M14 production. $69.00. Designed with full and semi-automatic capabilities, the weapon initially did not respond well to wet and dirty conditions, sometimes even jamming in combat. fragment) when fired from the short barreled M4 carbine (even at close ranges). The M16 was billed as self-cleaning (when no weapon is or ever has been). The Colt Model 655 M16A1 Special High Profile was essentially a standard A1 rifle with a heavier barrel and a scope bracket that attached to the rifle's carry handle. However, the rifle was initially delivered without adequate cleaning kits[37] or instructions because Colt had claimed the M16 was self-cleaning. Tactical Life. Cleaning kits were developed and issued while barrels with chrome-plated chambers and later fully lined bores were introduced. 80% lower receivers are extreme since they are partly finished products (80 percent), even without holes and milling. Best Reviews Magpul Industries Ctr Rifle Stock Mil Spec Ar15 M16 Up And Triggers There are so many machine shops machining mil-spec … [31] For a 7.62mm NATO rifle, the AR-10 was incredibly lightweight at only 6.85 lb empty. Because recoil does not significantly shift the point of aim, faster follow-up shots are possible and user fatigue is reduced. The M16 can also mount under-barrel 12 gauge shotguns such as KAC Masterkey or the M26 Modular Accessory Shotgun System. The rear sight can be adjusted in the field for windage. It means that the Spike has lowers with a milled shelf to allow the installation of a Registered Drop In Auto Sear (RDIAS). This item is extremely nice product. M16 Disconnector Tactical Solutions Group (0) $10.99 On sale: $9.99 Sale. It has been replaced by the M203 40 mm grenade launcher and nonlethal ammunition. As a lifelong gun owner he knows his stuff! With the advent of the M16A2, a new fully adjustable rear sight was added, allowing the rear sight to be dialed in for specific range settings between 300 and 800 meters and to allow windage adjustments without the need of a tool or cartridge. Instead, it had a low-profile iron sight adjustable for windage and a Weaver base for mounting a scope, a precursor to the Colt and Picatinny rails. The XM177 had a shorter 10 in (254 mm) barrel and a telescoping stock, which made it substantially more compact. The main selling point of Spikes M4 lower receiver is the capability to convert a regular semi-auto AR-15/M16 to selective fire gun with a drop in auto sear. The M16A4 is the fourth generation of the M16 series. [11][12] Adopted in July 1997, the M16A4 is the fourth generation of the M16 series. Because of anodizing blemishes the finish on these lowers varies quite a bit, ranging from greenish tinted black to dull, dark grey. There are two types of aluminum alloys of the T6 temper variety used in making AR-15/M16 receivers: 6061-T6 and 7075-T6. The M16 rifle, officially designated Rifle, Caliber 5.56 mm, M16, is a family of military rifles adapted from the ArmaLite AR-15 rifle for the United States military. Nickel Boron Complete BCG (2) $129.99 On sale: $125.99 Sale. The variants were issued in limited numbers to special forces, helicopter crews, Air Force pilots, Air Force Security Police Military Working Dog (MWD) handlers, officers, radio operators, artillerymen, and troops other than front line riflemen. The design was later changed to close the end to avoid this and became known as the "A1" or "bird cage" flash suppressor on the M16A1. The U.S. Army concluded that three-shot groups provide an optimum combination of ammunition conservation, accuracy, and firepower. The new stock included a fully textured polymer buttplate for better grip on the shoulder, and retained a panel for accessing a small compartment inside the stock, often used for storing a basic cleaning kit. Since its founding, Brownells has been a parts company, but from 2018 they started introducing their first line of firearms. [112] Note **: The horizontal range is the distance traveled by a bullet, fired from the rifle at a height of 1.6 meters and 0° elevation, until the bullet hits the ground. [74][75], In December 2006, the Center for Naval Analyses (CNA) released a report on U.S. small arms in combat. [37] Even President Kennedy expressed concern, so McNamara ordered Secretary of the Army Cyrus Vance to test the M14, the AR-15 and the AK-47. In Stock. [18] The M4's 14.5" barrel length reduces muzzle velocity to about 2900 ft/s. [citation needed], As a result, the Army was forced to reconsider a 1957 request by General Willard G. Wyman, commander of the U.S. Continental Army Command (CONARC) to develop a .223-inch caliber (5.56 mm) select-fire rifle weighing 6 lb (2.7 kg) when loaded with a 20-round magazine. The only major difference between the 601 and 602 is the switch from the original 1:14-inch rifling twist to the more common 1:12-inch twist. House. However, this design requires that combustion byproducts from the discharged cartridge be blown into the receiver as well. [18][19] However, early experiments with select-fire versions of the M1 Garand proved disappointing. The barrel profile under the handguards remained the same as the M16A1 for compatibility with the M203 grenade launcher. M4A1 - Carbine, 5.56 mm: MIL-C-71186 (AR) M16A2 - Rifle, 5.56 mm: MIL-R-63997B (AR) Last Modified on March 4. [14] The M16 uses an L-type flip, aperture rear sight and it is adjustable with two settings: 0 to 300 meters and 300 to 400 meters. Only 19 percent of M16 users (226 troops) reported a stoppage, while 80 percent of those that experienced a stoppage said it had little impact on their ability to clear the stoppage and re-engage their target. M16 Lower Receiver Specs And Composite Ar Lower Receiver get reduced [74] In tests conducted in 2005 and 2006 the Army found that on average, the new M4s and M16s fired approximately 5,000 rounds between stoppages. Military issue rifles are also equipped with a Knight's Armament Company M5 RAS hand guard, allowing vertical grips, lasers, tactical lights, and other accessories to be attached, coining the designation M16A4 MWS (or Modular Weapon System) in U.S. Army field manuals.[176]. This "partial fence" reinforcement is placed above the magazine release and just below the ejection port cover. Billet aluminum lowers are machined and milled from a solid block of pure aluminum on CNC machines. One note: you can also come across the term 7071-T6 aluminum in gun literature, but there is no such thing as 7071 aluminum, and that will tell you more about that “gun writer's” competence. [37][38][39] The U.S. also adopted the M60 general purpose machine gun (GPMG). The Pride of the Guard. Although this Brownells A1 retro lower is clone correct, some builders complain that it’s not as snug of a fit to the other manufacturers upper as it should be. [32] It had rugged elevated sights, an oversized aluminum[33] flash suppressor and recoil compensator, and an adjustable gas system. After a few minor modifications, the weapon gained in popularity among troops on the battlefield. Out of Stock. The C7 also features the structural strengthening, improved handguards, and longer stock developed for the M16A2. Many NATO member nations, but not all, subsequently developed or purchased rifles with the ability to accept this type of magazine. Otherwise it is externally identical to the M16A2. [98], The M16 rifle is considered to be very accurate. Quick view Retro Rifles. 1,188 troops were armed with M16A2 or A4 rifles, making up 46 percent of the survey. 60 percent (713 troops) were satisfied with handling qualities such as handguards, size, and weight. The U.S. military uses the Vortex Flash Hider on M4 carbines and M16 rifles. The M16 has a 500 mm (19.75 inches) sight radius. The 601 was adopted first of any of the rifles by the USAF, and was quickly supplemented with the XM16 (Colt Model 602) and later the M16 (Colt Model 604) as improvements were made. The Aero Precision Special Edition M16A4 Stripped Lower Receiver is the perfect solution for those looking for next clone build or an extremely close copy of the M16A4 currently used by the United States Military. Best For The Money is a Brownells AR-15 Blemished XM16E1 lower receiver. [29] Its NATO partners adopted the FN FAL and HK G3 rifles, as well as the FN MAG and Rheinmetall MG3 GPMGs. This is not a second just not completed to be called a lower receiver, or considered a firearm. [135], The M855A1 EPR may be green, and reports are still pretty thin, but it very well could be the ammunition the Army was asking for all along. After testing the AR-15 with the ammunition manufactured by Remington that Armalite and Colt recommended, the Air Force declared that the AR-15 was its 'standard model' and ordered 8,500 rifles and 8.5 million rounds. Scopes are mounted either by sliding them on from one end or the other; by means of a "rail-grabber" which is clamped to the rail with bolts, thumbscrews or levers; or onto the slots between the raised sections. As a result, the magazine follower tends to rock or tilt, causing malfunctions. Obviously, the semi-auto AR-15 models do not have three-position rotating selective fire switch like M16, but the selector switch has options only for “safe” and “fire”. Since Diemaco's acquisition by Colt to form Colt Canada, all Canadian produced flattop upper receivers are machined to the M1913 standard. After a few minor modifications, the weapon gained in popularity among troops on the battlefield. The rest of the barrel was maintained at the original thickness to enable the M203 grenade launcher to be attached. In 1964, the Army was informed that DuPont could not mass-produce the IMR 4475 stick powder to the specifications demanded by the M16. This Brownells M16A1 lower receiver comes with engraved markings: Model: BRN-16A1 Cal: 5.56mm Mfg: Brownells Inc. Maybe the best solution for completing your A1 Retro or Mil-Spec build is a Brownells AR-15/M16 A1 lower since this BRN-16A1 unit is an accurate reproduction of an A1 lower receiver with a fit exactly matching Brownells upper without wobble. [18] Lack of proper lubrication is the most common source of weapon stoppages or jams. The new handguards were also symmetrical so armories need not separate left- and right-hand spares. The M16A1 saw limited use in training capacities until the early 2000s,[165][166][167] but is no longer in active service with the U.S., although is still standard issue in many world armies. Both factors were attributed to high levels of soldiers performing their own maintenance. This easily recognizable receiver replicates the exact contours of that "Partial Magazine Fence" configuration and offers the perfect unit for a Retro build of the first M16 rifles issued to the troops in Vietnam. [128][141] The newer plastic magazines are about a half-inch longer. Without doubt, the color fill on the selector markings and the Spike’s spider logo engraving make this receiver a head turner and an eye-catching piece at the shooting range. Some tools are also necessary to build an M16. A new adjustable rear sight was added, allowing the rear sight to be dialed in for specific range settings between 300 and 800 meters to take full advantage of the ballistic characteristics of the new SS109 rounds and to allow windage adjustments without the need of a tool or cartridge. In addition, current model M16 flash-suppressors also act as compensators to reduce recoil further. Type a … You will, of course, also require a stripped-down lower receiver. LOWER RECIEVERS and LOWER KITS . [9][10] The M16A1 improvements include a bolt-assist, chrome-plated bore and a 30-round magazine. A NATO standardization effort soon started and tests of various rounds were carried out starting in 1977. The M16A2 fires the improved 5.56×45mm NATO (M855/SS109) cartridge and has a newer adjustable rear sight, case deflector, heavy barrel, improved handguard, pistol grip and buttstock, as well as a semi-auto and three-round burst fire selector. In fact, they feature only aesthetic issues due to the failure in the anodizing process. Parts were stamped out, not hand-machined, so could be mass-produced, and the stock was plastic to reduce weight. [17] Advocates for the AR-15 in the Defense Advanced Research Projects Agency acquired 1,000 Air Force AR-15s and shipped them to be tested by the Army of the Republic of Vietnam (ARVN). The forged lowers from NDS are later machined by Brownells to become the correct lower for replicas of early U.S. Army XM16E1 rifles or later released famous "XM177" Commando Carbine. Since the Spike's Tactical Complete AR-15 lower is made to the mil-spec dimensions for an optimal and precise fit, there's very little rattle or wobbling from a completed rifle using this lower. [73] In a 2002 assessment the USMC found that the M4 malfunctioned three times more often than the M16A4 (the M4 failed 186 times for 69,000 rounds fired, while the M16A4 failed 61 times). [18][121], With the development of the M16A2, the new 62-grain M855 cartridge was adopted in 1983. The Guard Experience. Solid billet lowers milled in CNC machine typically cost more than forged because of the extra machining time. [116] The 5.56×45mm NATO cartridge can also produce massive wounding effects when the bullet impacts at high speed and yaws ("tumbles") in tissue leading to fragmentation and rapid transfer of energy. 1969. p. 2326. 80% Aluminum Lower Receiver, with Mil Spec finish. Some of them were fitted with a Sionics noise and flash suppressor. United States. Colt also returned to the original "Commando" idea, with its Model 733, essentially a modernized XM177E2 with many of the features introduced on the M16A2. They also come in the "bullet trap" and "shoot through" types, as their names imply, they use live ammunition. The aftermarket M16 lower receivers may come in many styles and flavors with manufacturers offering assembled lower receivers, stripped lowers, or 80% lower receivers. With better mechanical properties, the 7075-T6 aluminum alloy is the option for anyone looking for superior strength and durability. The Spikes Tactical is the renowned manufacturer of complete firearms, but also they offer stripped and assembled AR-15 receivers' models. This second type lower also known as the "Partial Fence" type receiver has, unlike the first "Slabside" type, the captive pivot pins, which were held in place by a detent housed on the added reinforcement rib. [143] The M16's magazine has become the unofficial NATO STANAG magazine and is currently used by many Western Nations, in numerous weapon systems. Modifications to the M16A2 were extensive. GX. All current M16 type rifles can mount under-barrel 40 mm grenade-launchers, such as the M203 and M320. [127], However, there have been repeated and consistent reports of the M855's inability to wound effectively (i.e. [129] In 2006, a study found that 20% of soldiers using the M4 Carbine wanted more lethality or stopping power. REPORT OF TASK NO. [128] This reduced wounding ability is one reason that, despite the Army's transition to short-barrel M4's, the Marine Corps has decided to continue using the M16A4 with its 20″ barrel as the 5.56×45mm M855 is largely dependent upon high velocity in order to wound effectively. Length. [73] This affects the M4's timing and increases the amount of stress and heat on the critical components, thereby reducing reliability. The handguard retention ring was tapered to make it easier to install and uninstall the handguards. In U.S. Patent 2,951,424, the designer states: ″This invention is a true expanding gas system instead of the conventional impinging gas system.″ [81] Currently, the M16 is in use by 15 NATO countries and more than 80 countries worldwide. AR15 Lower Parts Kit – Complete. The Diemaco produced Weaver rail on the original C7A1 variants does not meet the M1913 "Picatinny" standard, leading to some problems with mounting commercial sights. The forged lowers are lighter than their billet counterparts and are the most economic chassis for an M16 rifle. Developed by the United States Army Armament Research, Development and Engineering Center and the Army Research Laboratory in 2013, it is tan colored with blue follower to distinguish it from earlier, incompatible magazines. While some lower receivers may look "cooler", and give your M16 a more refined feel, your rifle will operate the same whether they are built on a budget or exorbitantly priced receivers. [175] It features the M16A1 trigger group providing "safe", "semi-automatic" and "fully automatic" modes instead of the A2's "safe", "semi-automatic", and "burst" modes. Add to Cart. Lower receivers made in the casting process have a loose crystalline structure making them the weakest and not so aesthetically pleasing to the eye. and a Spikes ST-T2 tungsten heavy buffer. The rail comprises a series of ridges with a T-shaped cross-section interspersed with flat "spacing slots". [citation needed] The AR-15 used .22-caliber bullets, which destabilized when they hit a human body, as opposed to the .30 round, which typically passed through in a straight line. Mil-Spec M16 Lower Receiver: Description: Mil-Spec M16 Lower Receiver: Supplier part number: M16LR : Configure & Download; Rating & Comments (5) Tags (8) Alternate Versions . It is based on the M16, and was originally conceived as an improvement based on the Colt M4 carbine family issued to the U.S. military, with the notable inclusion of an HK-proprietary short-stroke gas piston system derived from the Heckler & Koch G36. M16/ A2 … The forging process makes the strongest aluminum form, which is very suitable for a heavy-duty M16 that you plan to use often. "The (M16's) Stoner system provides a very symmetric design that allows straight line movement of the operating components. Being similar to a complete lower, it is considered a firearm and subject to all laws. Buy Online keeping the car safe transaction. Meanwhile, the Army relented and recommended the adoption of the M16 for jungle warfare operations. The self-leveling/anti-tilt follower minimizes jamming while a wider spring coil profile creates even force distribution. [149] The initial flash suppressor design had three tines or prongs and was designed to preserve the shooter's night vision by disrupting the flash. The C7 has been developed to the C7A1, with a Weaver rail on the upper receiver for a C79 optical sight, and to the C7A2, with different furniture and internal improvements. Those features included: a muzzle compensator in place of the flash suppressor to manage recoil and allow for faster follow-on shots, though at the cost of noise and flash signature and potential overpressure in close quarters; a heavier and/or free-floating barrel to increase accuracy from 4.5 MOA (Minute(s) Of Angle) to potentially 2 MOA; changing the reticle on the Rifle Combat Optic from chevron-shaped to the semi-circle with a dot at the center used in the M27 IAR's Squad Day Optic so as not to obscure the target at long distance; using a trigger group with a more consistent pull force, even a reconsideration of the burst capability; and the addition of ambidextrous charging handles and bolt catch releases for easier use with left-handed shooters. [1][43] Inexplicably, the modification to the new M16 did not include a chrome-plated barrel. $145.33) SKU: CR250027264 UPC: Availability: ships from our shop in 5 to 8 days (+/-), after receipt of FFL from your local dealer. Intensive training programs in weapons cleaning were instituted including a comic book-style operations manual. The magazine chosen to become the STANAG magazine was originally designed for the U.S. M16 rifle. [171], The A2 uses a faster 1:7 twist rifling to adequately stabilize 5.56×45mm NATO L110/M856 tracer ammunition. [129] However, a minority of failures occurred in spite of multiple hits to the chest. 13A. The M16 was also adopted by the British SAS, who used it during the Falklands War.[164]. M16. Actually, 7075 has almost double the strength of 6061, but its hardness makes it more difficult to machine and typically it costs 2x as much as well. [9][72], After the introduction of the M4 Carbine, it was found that the shorter barrel length of 14.5 inches also has a negative effect on reliability, as the gas port is located closer to the chamber than the gas port of the standard length M16 rifle: 7.5 inches instead of 13 inches. Weight (with loaded 30 round magazine and sling) The development of the M16A2 rifle was originally requested by the United States Marine Corps as a result of combat experience in Vietnam with the XM16E1 and M16A1. … 125-126. When you are building an M16 on a budget, you can go with 6061-T6 aluminum since it is more than adequate in most situations but if you want the strongest and most durable material possible and the price is not an issue than the more costly 7075-T6 will be ideal solution for many firearms applications. Subsequently, it was the main reason why the military switched from 6061-T6 to 7075-T6 aluminum and not because the 7075-T6 receivers are "stronger", as many believe. The back part of the bolt forms a piston head and the cavity in the bolt carrier is the piston sleeve. [124] The NATO 5.56×45mm standard ammunition produced for U.S. forces is designated M855. [116], The M16's Vortex Flash Hider weighs 3 ounces, is 2.25 inches long, and does not require a lock washer to attach to barrel. McNamara ordered its adoption, despite receiving reports of several deficiencies, most notably the lack of a chrome-plated chamber.[58][1]. The U.S. military does not generally use rifle grenades; however, they are used by other nations.[163]. Made in USA Complete as an A2 lower or use as a. 71 percent (843 troops) were confident in the M16's reliability, defined as level of soldier confidence their weapon will fire without malfunction, and 72 percent (855 troops) were confident in its durability, defined as level of soldier confidence their weapon will not break or need repair. Enough M4s are already in the inventory to re-equip all necessary units by September 2016, and M16A4s will be moved to support[16][179] and non-infantry Marines.[180]. The Brownells blemished stripped lowers under manufacturer number 078-000-450WB are also often cheaper than regular ones because of small aesthetics imperfections such as discoloration and some anodizing flaws. The C7 is a further development of the experimental M16A1E1. Early model M16 barrels had a rifling twist of 4 grooves, right hand twist, 1 turn in 14 inches (1:355.6 mm) bore – as it was the same rifling used by the .222 Remington sporting round. Thread Status: Not open for further replies. The M16A1 was the finalized production model in 1967 and was produced until 1982. Firing Mark 262 Mod 0 ammunition with a 77gr Open tip Match bullet, the system has an official effective range of 600+ meters. It was equipped with triangular handguards, butt stocks without a compartment for the storage of a cleaning kit,[66] a three-pronged flash suppressor, full auto, and no forward assist. [31] The AR-10 featured an innovative straight-line barrel/stock design, forged aluminum alloy receivers and with phenolic composite stocks. It was replaced by the SAR 21, which was introduced during 1999 and 2000, but is still kept for reserve forces. [17] However, the Army Materiel Command criticized its inaccuracy at longer ranges and lack of penetrating power at higher ranges. "[147], In July 2016, the U.S. Army introduced another improvement, the new Enhanced Performance Magazine, which it says will result in a 300% increase in reliability in the M4 Carbine. "[108], Note *: The effective range of a firearm is the maximum distance at which a weapon may be expected to be accurate and achieve the desired effect. Configurations in service vary, but the core of the Mark 12 SPR is an 18" heavy barrel with muzzle brake and free float tube. When fired from a 20" barrel at ranges of up to 100 meters, the thin-jacketed lead-cored round traveled fast enough (above 2900 ft/s) that the force of striking a human body would cause the round to yaw (or tumble) and fragment into about a dozen pieces of various sizes thus created wounds that were out of proportion to its caliber. This is a by-product of the original design, where the carry handle served to protect the charging handle. ArmaLite entered the competition late, hurriedly submitting several AR-10 prototype rifles in the fall of 1956 to the U.S. Army's Springfield Armory for testing. The lengthening of the barrel was to support the attachment of Colt's own XM148 40 mm grenade launcher. [90] A rifle's perceived recoil is also dependent on many other factors which are not readily quantified. U.S. Government Printing Office. If we neglect cast lowers as parts of doubtful value and futuristic polymer receivers of limited durability than we have to choose traditional materials and technological processes. The South Vietnam soldiers issued glowing reports of the weapon's reliability, recording zero broken parts while firing 80,000 rounds in one stage of testing, and requiring only two replacement parts for the 1,000 weapons over the entire course of testing. Developed to increase the effective range of soldiers in the designated marksman role, the U.S. Navy developed the Mark 12 Special Purpose Rifle (SPR). This tube relieves pressure on the barrel caused by standard handguards and greatly increases the potential accuracy of the system. [37][47], In 1969, the M16A1 officially replaced the M14 rifle to become the U.S. military's standard service rifle. The M16A1 was especially lightweight at 7.9 pounds (3.6 kg) with a loaded 30-round magazine. expatqatar04 Member. As more units adopted the AR-15, Secretary of the Army Cyrus Vance ordered an investigation into why the weapon had been rejected by the Army. Unfortunately it was prone to breakage and getting entangled in vegetation. Later, the chrome plated carriers were dropped in favor of Army issued notched and parkerized carriers though the interior portion of the bolt carrier is still chrome-lined. We would recommend this store in your case. The HEL M4 vented gas directly from the action, requiring a modified bolt carrier. Various other changes were made after numerous problems in the field. The market is full of various M16 lowers assemblies and lower receiver part kits, but you’ll probably need to know a few basic pieces of information about various lowers types, materials, and configurations. With these and other changes, the malfunction rate slowly declined and new soldiers were generally unfamiliar with early problems. He ordered the Army inspector general to investigate the testing methods used; the inspector general confirmed that the testers were biased towards the M14. Due to the process of forging metal, there can be slight surface imperfections like indentations. This is a Receiver Made by NoDak Spud (NDS), The Fit Isn’t so Tight With Some Upper Receivers, A Solid Lower for the Original XM16E1 Rifle at a Budget Price, Completely Stripped Reproduction of an A1 Receiver, Machined by Brownells to the Same Spec as the Company's Full-Price Options, You may Encounter a Large Wiggle Between the Lower and Upper Receivers, These Blem Lowers may have the Safety Markings on Both Sides of the Lower, Three Position Color-Coded Bullet Selector, It Has Low Shelf Making it RDIAS Compatible, MIL-A-8625F Type III Class 2 Hard Coat Anodized Finish, Mil-Spec Buffer Tube With ST-T2 Tungsten Heavy Buffer, It Has Safe, Semi, Auto Selector Markings, Features Markings “Property of USA” and “Cal.
