NOTE- The Nickel Boron coating is well known for reducing friction because of its molecular structure, it offers great heat dissipation properties, reduces wear on the BCG and the corresponding parts, and it increases the longevity of the BCG. Nickel Boron coatings are also known to reduce problems with function due to the decrease in overall friction and wear.

Both bcg's are well made. No problems, over the previous ones. Good value. Freind has same issues with old BCG'S. Failure to feed; no lock up. If I had other platforms these would be the go-to items.

Great product, reasonable price.
I’ve yet to have an issue with Toolcraft BCG’s. Everyone has their preferences, but for me, this just works reliably at a great price point. I regularly maintain my rifle, but I’m not “easy” on it either, and this thing just chugs away.

Just what I was looking for
This was just what I was looking for. I've always wanted a silver bcg. The lifetime warranty was a big selling point for me. My only complaint is I wish they put a matching firing pin (NiB coated) in it, even if it hopped up the price a few dollars.

Everything I expected it to be
BCG was the best priced at AR15discounts. Service was excellent. Product came undamaged and quick. It is ToolCraft quality which I never have an issue with. First time using Nickel Boron though. So far, seems great. Easy cleaning after as well.
