Most Helpful Positive Review No hiccups!
I just put 500 rounds through mine. Not 1 failure, either with my Huxwrx can or without . I know it's not the quietest suppressor, but it's a laser with it. We were shooting at a steel plate at 100 yards. I hit it 250 times, with a Romeo 5. The other 250 were at various distances. A hit every time. Hearing that steel "clang" sound is very satisfying. I am very happy with this upper. 5 Stars! *****

Perfect for custom AR

by Edgar, Verified Owner from CA, United States Written on July 19, 2025
Found the fit and finish to be very good, 500 rounds malfunction free. Time will tell on reliability, but so far so good. Overall I'm happy with it.

Great product. The muzzle device is not pinned and welded. It’s a nice qd adapter but wasn’t compatible with my suppressor
