If you are looking to build a 9mm rifle, then this bolt is exactly what you need to ensure smooth cycling with any standard fire control group. Our bolts come with ramps in a nitride finish.

Designed to work with Colt & Glock Mags. This bolt also uses colt extractors & firing pins so when it comes time to replace a wear part you will easily be able to find the replacement part, unlike some 9mm BCG's on the market that use proprietary extractors and firing pins.

Tungsten weighted to proper spec for reliable and safe use.
