Nitrided 9310 bolt manufactured by Rubber City Armory
These bolts are headspaced checked with a barrel which has been selected due to its precise fit with a PTG 300blk barrel extension go-gauge. This is to ensure there will be no headspacing issues caused by our bolts. We still highly recommend headspacing this bolt to your barrel as we can only ensure that the bolts themselves are in spec.
These bolts come pre-installed with Sprinco ejector and extractor springs.
The gas key on this BCG also supports the use of POF’s roller cam pin if you would like to reduce friction even further!
These bolts are nitrided by H&M Black Nitride.
