Nearly two decades of building the finest custom tactical AR-15 rifles have given us the insight to develop a comprehensive line of stainless steel, match grade barrels that offer superior accuracy, reliability, and longevity for your next custom AR rifle project. All Wilson Combat Match Grade AR-15 barrels are precisely crafted from the finest American-made 416R rifle rated steel on computer controlled equipment to our exacting list of technical specifications. These proven barrels feature a hand-polished bore and then complete a rigorous final inspection process that ensures your new barrel will meet your most demanding expectations. All barrels feature crisp CNC markings, precision muzzle crown and a chamber optimized for reliability. Our AR-9 9mm AR pistol/carbine barrels are made with the same care as our legendary rifle caliber barrels. These superb barrels are perfect for your next build and have been designed to work with most legacy 9mm AR uppers. The 1-10” twist is optimized for long range accuracy and 1” groups at 50 yards are not uncommon with match grade ammunition. These barrels use a 5/8”-24 TPI threaded muzzle for enhanced accuracy and work well with our Q-Comp muzzle brake. Our AR-9 Barrels are compatable with Colt, JP, and Stag upper recievers.
