Faxon Firearms
Overview
The Faxon Firearms 9mm AR-15 Bolt Carrier Group is designed specifically for use with Glock or Colt magazines, making it a versatile choice for builders looking to chamber their rifles in 9mm. The nitride finish enhances durability and provides a smoother cycling experience, which is crucial in blowback gas systems typically used in 9mm builds. This BCG is often found in pistol-caliber carbines, where reliable feeding and ejection are paramount for optimal performance.
