The TacFire BCG-NIB AR15 223/556/300BO Bolt Carrier Group delivers a smooth, dependable cycling solution for AR-15 and M16 pattern rifles. Built around an M16-style carrier machined from 8620 tool steel and paired with a 9310 tool steel bolt, this nickel boron coated assembly is engineered for long-term durability and easy cleaning while supporting full-auto compatible setups.

This bolt carrier group is optimized for 5.56 NATO, .223, and .300 Blackout builds where reliability and reduced maintenance are priorities. Shot-peened, MPI-tested components and a corrosion-resistant nickel boron finish make it well suited for range use, training, and general-purpose rifle builds. TacFire’s attention to material selection and Mil-Spec heat treatment standards is evident throughout the design.
