“I bought this bolt for a 6.5 grendel upper build a little over a year ago. I have put several hundred rounds through it since. The coating on the bolt makes it run smoothly and the carbon cleans off the surface effortlessly. I will definitely be buying more of the Toolcraft bolts for future builds.”
“BCG is first quality as advertized. Nitride finish is excellent. Part interface is smooth and slick. Runs great. 70+rounds with no hickups. One of the nicest BCG's I have seen.”
