Nitride .45ACP AR Bolt for Pistol-Caliber Carbine Builds
The .45ACP AR Bolt Nitride is built for AR-pattern pistol-caliber carbine platforms, supporting builders assembling a dedicated PCC upper or completing a full build. The nitride finish adds surface hardness and corrosion resistance to help maintain consistent cycling and extraction, while making routine cleaning and maintenance more straightforward. It is manufactured in the USA to mil-spec standards for individual builders and shops alike.
Because PCC setups vary between manufacturers, confirm fitment with your specific barrel, upper receiver, and feed system before assembly, and inspect each component during the build to verify proper function. Builders working across other chamberings can compare an additional pistol-caliber AR bolt option or a further nitride pistol-caliber bolt for their planned configuration.
To round out a build, pair this bolt with supporting parts such as an AR15 nitride cam pin. Review the listed specifications and confirm magazine well alignment for your chosen magazines before final assembly.
