A Nickel Boron BCG is possibly the ultimate upgrade to the All-American AR-15. Nickel Boron is an extremely durable finish with self-lubricating properties so your AR-15 cycles smoother and requires less lubrication. And it looks good too!
Use caution when removing your new Nickel Boron Bolt Carrier Group from it's packaging. The light film of oil these ship with is enough to make it slip right out of your hand. See more DETAILS below.
Toolcraft is a major OEM manufacturer of bolt carrier groups for the U.S. Military and many large firearms manufacturers. We buy direct from Toolcraft and pass the savings on to you. You get OEM quality without the logo and the steep markup.
