“This was my first nickel boron coated bcg so I wasn't sure what to expect. This thing is really slick, there are no sharp edges like some of the cheaper bolt carriers, and has a nice polish on it. The gas key was staked well. only complaint is the side of the gas key could have been a little smoother along with the cam pin, but nothing that 2min with 600 grit won't fix, this from a guy that takes apart every gun and polishes each bearing surface. I will definitely buy these for future builds.”
“Toolcraft is the only bcg’s I will use. Great fit and finish, no machine marks, properly steaked and all at a great price with a lifetime warranty. Can’t beat toolcraft.”
“Haven't been able to install it into my rifle yet. Still waiting on other parts. But, aesthetically, looks great. No blemishes or discoloration in finish. Looks and feels exactly like it should.”
