Geissele Automatics Rifle Bolts for Sale

Within Rifle Bolts, Geissele Automatics LLC of the United States moved to fully in-house AR-15 bolt components with its Super Duty rifle program in 2019, and by 2021 was shipping rifles with its own Reliability Enhanced Bolt Carrier Group paired with a forged Stressproof Bolt, both also offered as standalone parts.
