Installed on a brand new never fired AR15. Did my routine cleaning and lube to the rifle and BCG. Took it out to get the range and 800 rounds later it functioned flawless! The heart of every AR you a the BCG glad I swapped out the mil spec for this. From order to delivery it was flawless.

This was my first build, I couldn't be more pleased, When you use good products like Sharps than you build dependable guns.

Fast service received today all appears good. Will know if it fire as good as it looks. 11/28 first nickle boron. Dlc is great
