The AR-15 bolt assembly is, as are all of our house brand spare and replacement parts for the AR-15 platform, a brand new part produced in a state-of-the-art manufacturing facility that holds several foreign military contracts. As such, all parts are compatible with and interchangeable in any MIL-SPEC AR-15.

Located within the bolt carrier group, the AR-15 bolt assembly is an essential component that facilitates the firing sequence, as it is responsible for extracting spent cartridges from the chamber and ejecting them from the receiver as well as stripping and inserting fresh cartridges. This is accomplished as the bolt carrier group is cycled back and forth between each discharge, pushed to the rear by expanding propellant gases and thrust forward by the buffer assembly and recoil spring. It is secured within the bolt carrier group via the bolt cam pin.

  1. Good Bolt at a Good Price review by NM on 9/10/2013

    I've ran this bolt for several hundred rounds in a couple different bolt carriers with no issues. It is a good mil-spec bolt assembly and a good value. Combine this with a bolt carrier and firing pin and you have a nice budget BCG. Would buy again.
