Most Helpful Positive Review cryptic low mass bcg
Runs great for subsonic 300 blk. Seems to be gas efficient. Perfect for a low recoil build coupled with an adjustable gas block, reduced power spring and a 1.7 ounce buffer I had zero malfunctions. Works with an FRT but needs a h1 to reduce bolt bounce and light primer strikes.
