The Ruger AR-556 Pistol is a robust, tactical firearm featuring a 10.5-inch cold hammer-forged barrel crafted from 4140 chrome-moly steel with a 1:8 twist rate. It is designed with a direct impingement gas system and a 9-inch free-floated handguard equipped with M-LOK slots on the sides and bottom, and a Picatinny rail on top. The upper receiver includes traditional features such as a brass deflector, forward assist, and a dust cover, while the slick top configuration lacks backup iron sights. The pistol comes with a 30-round Magpul PMAG and an SB Tactical SBA3 adjustable brace for customizable length of pull. The trigger is mil-spec, offering a solid break with a 7-pound pull and a tactile reset. The Ruger AR-556 Pistol employs a unique bolt carrier group, inspired by older Colt designs, featuring a notched hammer to prevent slam fires in malfunction scenarios. The pistol’s flash hider, which includes slats around its circumference, helps mitigate muzzle flash. It is also threaded for suppressor attachment to reduce noise and flash.
