The SIG M400 Series Tactical AR pistol, designed for use in law enforcement, military operations, or as well as competitive shooting. The SIG M400 is a true AR platform tactical pistol. Provides unparalleled accuracy, with a 11 chrome-lined and phosphate coated barrel that provides maximum durability and corrosion resistance. A 7075-T6 aircraft grade aluminum forged lower receiver adds to the durability and reliability.
This firearm features a direct impingement gas-operating system with rotating locking bolt and a two-piece aluminum quad-rail. It also includes the new SB-15 pistol stabilizing brace*, which dramatically improves the single-handed performance of buffer tube equipped pistols and is ATF compliant, veteran designed, quick and easy to install, and made in the USA.
*The ATF has reviewed this product and determined that attaching the SB15 to a firearm does not alter the calssification of the firearm or subject to the firearm to NFA control.
This AR pistol is built like a tank but is light and easy to shoot. Out of the box I can shoot 4 groups at 25 yards. At 50 yards a Burris 5X scope & bench rest shooting, I can keep 2 groups. This pistol shoots better than me and not one malfunction after 1000 rounds.
