Probably not, but the system was castrated by the poor choice of ammunition and insane lack of cleaning gear. Was the Colt AR-15 that was designated M16 sent into combat prematurely?

In some cases, the cartridge case would stick in the chamber-sometimes during combat operations. They also increased extractor tension to help in extracting the cartridge. The problem was met with a recoil device with an вЂњinternal plurality of massesвЂќ that was geared for the ball load. Modifications and ImprovementsД¬olt was asked to modify the firearms to function with ball powder-loaded ammunition. One was to issue cleaning kits and a comic book-type cleaning manual. The Army entered into several knee-jerk fixes. The AR was not originally issued with cleaning gear! Even the original low-maintenance rifle, the M1 carbine, needed cleaning frequently. Worse, after the problem was identified, the Army did not withdraw the ammunition from service in Vietnam. The result was a different pressure curve and clogged gas ports. The Army specified that the same ball powder used in the 7.62mm NATO cartridge be used in service ammunition. The original 5.56mm loading was developed for a clean burn and high energy. Soldiers on long patrols could carry a lot of ammunition.Д«ut Army Ordnance made a grievous error (that Congress later concluded verged on criminal negligence). When the rifle was issued in Vietnam, the lightweight, accuracy, controllability and easy firepower were greatly appreciated. The gas doesnвЂ™t operate by a piston-at least in the vast majority of the rifles-but the gas is led directly to the bolt in this gas impingement system. This young Major is firing the Colt AR-15 carbine and finding it good. Low recoil, longer range than pistol caliber carbines, and control in fully automatic fire were important parts of the Stoner design. The AR cartridge was developed from a high-velocity varmint round, the. The M16 was designed as a counter to the fully automatic AK-47 rifle. The rifle was developed by Eugene Stoner and the contract was awarded to Colt to produce the rifle. Those of us that have a choice of any weapon system most often choose the AR rifle. Note the Israelis have their own Galil and thousands-perhaps hundreds of thousands-of captured AK-pattern rifles. The rifle is the first choice of top-notch security teams and armies. (Rifles on the front line are a different matter.) Yet they continue to serve. For this purpose it is modified with several holes drilled in the side, which are used to pin spacers in place to hold the smaller 9mm magazine in the standard 5.56mm magazine well.Many of the rifles in use in training our young warriors are older than the soldiers using them.

The full fence lower (both A1 and A2) is also the receiver used on Colt's 9mm SMG. However, due to the difficulty in identifying them from a distance and the fact that different manufacturers use slightly different designs (such as strengthening around only the front push pin or omitting the selector markings on the right side of the weapon), these have been treated as one variant for the purpose of identification. The design of this lower was upgraded with the adoption of the M16A2 featuring strengthening around the front and rear receiver push pins and fire selector marking on the right side of the receiver. It can be identified by the raised fence around the magazine release button on the right side of the weapon which is designed to lessen the chances of accidentally releasing the magazine. The full fence lower is the standard receiver used on all AR-15s since the M16A1. The preferred term for identification, be it the model name or simply the model number, is highlighted in bold. Due to the large number of companies that make AR-15 pattern rifles that are nearly indistinguishable from the original variants, all rifles should be identified using Colt terminology in the absences of any information to the contrary, such as unique parts or visible receiver markings. This is not a complete list of all variants produced by Colt, and only contains those variants that have appeared in media. This page is intended as a guide to identify the various Colt manufactured M16 variants and derivatives.
