Colt ACR for sale
The Colt ACR is based on the M16A2 platform, with modifications made to the design. The first is a muzzle brake/compensator system designed by Knight’s Armament Company meant to reduce muzzle rise, also reducing the rifle’s report by 13.5 decibels. The weapon also features a oil spring hydraulic buffer designed to lower perceived recoil of moving parts during automatic fire. Recoil is reduced to 40% of that of the M16A2 as a result. It also has a six-position telescopic buttstock.
The Colt ACR is gas-operated and uses exactly the same rotating bolt system as the M16A2. The handguard, pistol grip and buttstock have all been redesigned to improve handling, and the handguard incorporates a top rib which allows instinctive shooting in a manner similar to handling a shotgun.
The Colt ACR is fitted with a very advanced muzzle brake/compensator which, together with a new oil-spring buffer in the receiver, reduces recoil to about 40 percent of that of a standard M16A2 rifle. The firing mechanism permits single shots and full automatic fire, but there is no three-round burst facility.
The key design of the Colt ACR was the use of “duplex rounds“, a single cartridge with two bullets in it. Olin Corporation produced three different rounds for testing, the first consisting of two tungsten projectiles in a long–necked case, the second used a standard–length case with two 27 grain (1.75 g) 0.158–inch (4 mm) tungsten projectiles, and the final entry was another standard–length case with two 0.224–inch (5.69 mm) projectiles, one 35 grains, (2.27 g) the other 33 (2.14 g). The latter was eventually selected for submission to the Colt ACR trials. The basic idea of the duplex load is to increase the number of projectiles fired, which is the primary determinant of battlefield casualties. However, they significantly reduced accuracy, requiring the user to also carry traditional ammunition for long–range shots.
