are fully compatible with Glock or Colt style lower receivers.
Carolinas First Defense CFD-9mm SP4 Coated BCG is designed
to provide reduced friction coefficient that not only lowers operating
temperatures but also increases overall performance as well as the Bolt Carrier

BCGs will increase lubricity and wear resistance while providing a smoother
recoil, improved consistency, faster cyclic rates and reduce carbon fouling.
