JP Enterprises .308 AR EnhancedBolt High Pressure Bolt & Firing Pin Assembly


Criterion Barrels offers complimentary headspacing services with each bolt and barrel set purchased. These High Pressure bolts feature a smaller firing pin channel than standard DPMS pattern .308 AR bolts, minimizing primer pocket flow with higher pressure loads. We find this to be beneficial with some of the hotter 6.5 Creedmoor factory loads currently on the market.
