This is a build that I did a few months ago from psa. It’s a 10.5 inch fluted barrel with a silencerco asr muzzle brake, Stinger 10 inch free float handguard , sig Romeo red dot and magpul buis, magpul pistol grip, psa blem lower, maxim pdw brace and 2 20 round mags. It’s had probably 100 rounds through the gun and it hasn’t had a malfunction yet.
