All Wilson Combat Match Grade AR-15 barrels are precisely crafted of 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 feed ramps 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 and gas port optimized for reliability. .223 Wylde is a hybrid .223/5.56 chamber designed by Bill Wylde to yield the accuracy advantages of the match .223 Remington commercial chambering but without pressure or reliability failures when using high velocity 5.56 NATO spec ammunition. The .223 Wylde achieves better accuracy by having a chamber throat that is tighter than 5.56 but will still function reliably with military 5.56 ammunition as the case dimensions are the same.
