Arm or Ally AR15 / M16 5.56 NATO Bolt Carrier Group w/ C158 Bolt – Black Nitride

100% Made in America

Arm or Ally M16 / AR15 Bolt Carrier groups in 5.56 NATO are precision ground, properly heat treated, full-Auto M16 BCG, manufactured using the finest U.S sourced raw materials. The Black Nitride finish vastly increases the hardness of the steel, prevents corrosion, is highly resistant to wear, will not flake (it’s not a coating, it’s a bond), and has increased lubricity when compared to a phosphate-finished BCG. The Bolt Carrier Group is the heart of your rifle, and if you want to upgrade the reliability and functionality of your rifle, this is a great way to do it!

Since 2015, Arm or Ally has handled hundreds of thousands of bolt carrier groups and was the leading dealer of the Toolcraft BCG. Trust us when we say, “we know bolt carrier groups”! We have chosen specific manufacturers for each component of our BCG due to their high-quality parts and attention to detail. For this particular BCG, we leave off the fancy logos and packaging and deliver you a best-in-class BCG for a very attractive price.

What is the Arm or Ally Brand?

Our promise to you is a high-quality product at a more affordable price—100% American-made products backed by the same defect-free warranty as every other product we offer.

...unless you like paying for their marketing and fancy packaging!
