A3FSSTB20R1) is a Louisiana-built AR-15 pattern rifle with a patented forward charging system. Bilson Arms fits it with an 18-inch 416R stainless steel barrel, a 1:7 twist and a rifle-length direct impingement gas system.

Key Specifications

• Caliber is 6mm ARC, a cartridge that stays supersonic at long range from an AR-15 size action.
• The barrel is 18 inches of 416R stainless steel, chosen for accuracy and barrel life.
• Rate of twist is 1:7, a rate that stabilizes the heavier 6mm bullets.
• The action is semi-automatic direct impingement, with a patented forward charging handle system.
• The gas system is rifle length, which gives a smoother recoil impulse and consistent long-range cycling.
• The receivers are billet aluminum with a zero-play fit, backed by a 1 MOA guarantee.
• The handguard is a free-floating M-LOK, which leaves the barrel unloaded for accuracy.
• The muzzle device is an A2 birdcage on a 5/8×24 thread.
• Furniture is from B5 Systems, including the buttstock and pistol grip.
• The finish is a two-tone Cerakote in Tungsten Gray and Gunmetal Black.
