The Wilson Combat Match Grade Barrel (brand part number TR-300SBRPG8RT7) is an 8 inch .300 AAC Blackout barrel built for AR-15 platform rifles, precisely crafted from American-made 416R rifle-rated stainless steel on computer-controlled equipment to a demanding technical spec. Wilson Combat hand-polishes the bore and feed ramps, and every barrel gets crisp CNC markings and a precision muzzle crown for consistent accuracy. The chamber and gas port are optimized specifically for reliability, giving this barrel the same match-grade attention to detail that Wilson Combat is known for on its complete rifles.
