Purpose-built for 10mm AR-15 pistol caliber carbines, the Faxon Superfinished 10mm PCC Blowback Full-Mass BCG delivers the proven features of our well-loved 9mm PCC carrier—scaled up for 10mm performance. It maintains Glock® magazine compatible geometry, a user-removable weight, and full-auto compatibility while incorporating modern upgrades for durability and easy service.

Competitive shooters and plinkers alike will appreciate the ramped bottom, designed so many common triggers can be used. The extractor is upgraded to an AR-15 pivoted and sprung option. For easier disassembly, a standard firing pin cotter pin is used. And for long-term durability, the carrier key is separate from the charging surface, helping prevent key damage from vigorous manipulation. A stronger firing pin rounds out the improvements.

Finished in salt bath nitride, this BCG is built to resist corrosion, reduce friction, and run smoother with less fouling.

Frequently Asked Questions

Yes. This carrier uses Glock®-style magazine compatible geometry for Glock-pattern PCC lower receivers.

What does “full-mass blowback” mean?

Will it work with common triggers?
The ramped bottom is designed to work with many common trigger designs, making it a solid option for competition and range use.
