Received this and added it to a lower shoot 100 rds and then took to a match. Floating hand guard floated off on the second string. Three screws holding it on backed out. No locktite seen on threads. Hour drive to match and fees wasted. Should have assembled it myself.
Runs fine now after locktiting the screws.
