Product Description

  • Enhanced Bolt Carrier Group is designed to reduce carrier tilt/cant during recoil and increasing reliability by strategically relocating key bearing surfaces. The enhanced carrier has fewer points of contact resulting in less friction and keeps debris from interfering with function
  • The QPQ nitride/melonite treatment hardens the surface to 70 RC and reduces friction as well as adding corrosion resistance inside and out
  • Superior to chrome lined and parkerized bolt carrier groups
  • MPI and HPT with 9310 bolt nitride/melonite treated
  • Requires very little lubrication and has a very slick surface
  • Corrosion resistance inside and out
  • Side staked gas key with grade 8 fasteners
