The bolt carrier group (BCG) is an area where there is no room for shoddy manufacturing. Build your AR15 with the very best with this black phosphate bolt carrier group from Phase 5 Tactical.

Like all Phase 5 Tactical products, this piece is designed to withstand serious use, and it is manufactured with advanced machining procedures. The tight tolerances ensure a perfect fit and smooth functioning on your AR15. Black phosphate coating is applied for supreme resistance to gas erosion and corrosion caused by external elements. In addition, it minimizes the friction when cycling. It also serves to decrease the visibility of your weapon; it does not reflect light like other common finishes. The inner surface of the bolt carrier is lined with chrome for a robust defense against fouling and corrosion. The Phase 5 Tactical logo is laser-etched on the visible side.

This Phase 5 Tactical bolt carrier group is convenient and affordable option for your build.
