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.

USI bought two of these after I discovered Cryptic Coatings uses Toolcraft BCG for their wares. Not as nice as Cryptic but an outstanding BCG for the money.
USLooks great and worked perfectly. Very slick, better than the older mil spec BCG I had.
USThis BCG has a nice finish, works smooth. A nice upgrade
USBoth 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.
USI’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.
