Ruger AR556 Pistol 8570

  • Lower receiver is fitted with an adjustable SB Tactical® SBA3® Pistol Stabilizing Brace® to aid in accuracy, balance and recoil management.
  • Handguard is free-floating for accuracy and the slim, 9″ length provides enhanced ergonomics and support. Magpul® M-LOK® accessory attachment slots along the 3:00, 6:00 and 9:00 positions.
  • Made from aerospace-grade 7075-T6 aluminum forging, the flattop upper receiver includes a forward assist, dust cover and brass deflector.
  • Bolt is machined from 9310 alloy steel and is shot peened and pressure (proof) tested to ensure strength, structural integrity and durability.
