Aero Precision Nickel Boron 5.56 BCG

Aero Precision’s NiB bolt carrier group features more than just a chrome-like finish. The bolt receives magnetic particle inspection (MPI), and is shot-peened to ensure surface hardness. The tool steel extractor provides reliable extraction, enhanced by a Viton O-ring around the spring. Plus, the gas key is secured with Grade 8 hardware, and properly staked to ensure durability.

Ultra-Slick Nickel Boron Finish

Nickel Boron imparts a number of benefits to your AR-15. The slick surface makes the entire BCG ride smoother inside the action, reducing wear on the upper receiver. Not only that, that shiny exterior also makes it extremely easy to clean the bolt, with most carbon buildup able to be wiped away with just a cloth between range days.
