The Corsair Sports 5.56 AR Pistol has been upgraded for 2020 with the popular SB-Tactical SBA3 5 position adjustable arm brace. This stabilizing brace is extremely durable and rigid with plenty of adjustment for different arm lengths and features a QD sling swivel slot for carrying or added stability when shooting off hand. It also allows for a proper cheek weld giving you a variety of ways to shoot your AR pistol. This model comes with a 10.5” barrel machined from 4140 Chrome Moly steel with a Melonite finish and a 1:7 twist rate. M4 feed ramps help to angle the cartridges into the chamber and help to prevent FTF malfunctions. The Corsair Sports 5.56 pistol paired with the SBA3 stabilizing brace make this gun extremely fun at the range.
