The AR6951 is a civilian reproduction of the R6951. The 6951 is a modernized variant of the M635 series, known most famously as the Colt 9mm SMG, and features a 16-inch barrel with a modernized flat-top rail for mounting optics. The R6951 has been deployed with many law enforcement agencies across the United States, and has also seen use as a service weapon for security personnel stationed at nuclear power plants. The straight line construction coupled with the low recoil of the 9mm cartridge and buffer system of the AR-15 platforms allows for highly accurate fire. The 6951 operates similarly to most AR-15 platforms allowing for ease of use. This model features a classic black anodized finish and comes with one 32-round magazine.
