U.S. Military Firearm History!

The Colt Commando was an outgrowth of the CAR-15 Military Weapons System, specifically the Model 607, as a result of interest by the U.S. Army for a fully developed weapon. It was introduced by Colt in 1966 in response to the US military's desire for a shorter M16, without the Model 607 SMG's inadequacies. Colt engineer Rob Roy designed a simpler two-position telescoping tubular aluminum buttstock to replace the complicated extending triangular version. The fragile and ad hoc triangular handguards were replaced by reinforced round handguards. Each half of the round handguard is identical, simplifying logistics by not requiring a top/bottom or left/right pair. The Model 609 Commando has a forward assist, while the Model 610 Commando does not. A Model 610B with a four-position selector was available, but not used by the U.S. military. All versions are equipped with the 4.25-inch (108 mm) long moderator.

The XM177 uses a unique flash suppressor, sometimes called a flash or sound moderator, for its 10-inch (250 mm) barrel. This device is 4.2 inches (110 mm) long and was designed primarily as a counterbalance measure as the shorter barrel makes the weapon unwieldy. This device reduces flash signature greatly and sound signature slightly, making the normally louder short-barreled carbine sound like a longer-barreled M16A1. Although it has no internal baffles and does not completely reduce the sound signature to subsonic levels, because it alters the sound level of the weapon, the US Bureau of Alcohol, Tobacco, Firearms, and Explosives has declared this muzzle device to be a sound suppressor and regulates its civilian purchase in the United States.

The Model 610 was classified as the XM177[7] but adopted by the Air Force as the GAU-5/A Submachine Gun (GA denoting an automatic gun and U a complete unit rather than a parts kit: the popular "gun aircraft unit" and "gun automatic unit" explanations are backronyms[8]). The Army purchased 2,815 Model 609 CAR-15 Commandos on June 28, 1966, which were officially designated Submachine Gun, 5.56 mm, XM177E1.[7] As part of the contract, Colt was supposed to supply each XM177E1 with seven 30-round magazines, but Colt was unable to build a reliable 30-round curved magazine that would fit in the M16 magazine well, so most XM177E1s were shipped with 20-round magazines. The exception was the 5th Special Forces Group, which received a total of four early 30-round magazines. Colt completed delivery of the purchased XM177E1s in March 1967, but the 30-round magazines did not become available until November 1967.

A collaborative partnership between Cyma CGS and Colt, licensed by Cybergun, the Colt M610 XM177E1 utilises the CYMA CGS Gas System, a collaborative effort with T8 (SP Systems) in replicating and retrofitting the venerable Tokyo Marui MWS M4 / AR-15 series of gas airsoft rifles, reinforced with steel internals for better durability and an adjustable trigger box. Because of this, you could expect this rifle to perform well, and you have the backing of a plethora of aftermarket support. The XM177E1 M610 comes with a 20-round gas-powered short magazine and is a 1:1 replica of the CAR-15/XM177E1 platform
