Machined from certified 416R stainless steel for superior strength, durability, and accuracy. Barrels are match grade, hardened to 40-42 HRC and cut broach rifled to shoot jacketed or lead bullets. All barrels are chambered for full case support. All barrels are manufactured for glock drop in and will only occasionally require modification to fit. Extended lengths are available, as well as ported and threaded options. Two port options are extended barrels with ports beyond the end of the slide.
