CNC machined with slightly oversized dimensions for tighter barrel lockup and a "Match Quality", drop-in fit. Premium stainless steel bar stock is machined, heat treated and cryo stress relieved before final rifling to improve accuracy and barrel life. Precision, broach cut rifling gives outstanding accuracy with all bullet types, including lead. Complete kit includes pre-fit, match-grade barrel, bushing, link and pin for faster installation. May require minor fitting. Mfg: Ed Brown
