Manufacturing details that will provide a precise fit, increased lockup area, and improved accuracy. The addition of a full Wilson/Nowlin style ramp will also offer consistently reliable feeding. The bore has been button rifled and air gauged to ensure the exact bore size and finish. Rifling is 6-groove with a 1/16" twist.
