“I have a dozen toolcraft bolt carrier groups in a wide variety af arms and they have all worked perfectly! I like the smooth surface of the nickel Boron, as they are easier to clean, but performance is the same. It works great and the rifle is very accurate with it!”
“Great quality for a great value. Run several AR10s only with these HP 6.5 bcgs. Adjustable gas blocks running down on gas, throw them far and fast with these double electors.”
“I have had very good results form every tool craft BCG that I have. Love the Nickel Born finish as it is easy to clean.
I plan of swapping out my other BCG to the Toolcraft Nickel Boron BCG over time.”
