I ordered AR-15.50 Beowulf Tank Style Muzzle Brake on 3/18 received it 3/29 in a envelope not wrapped up or anything just loose and flopping around and was missing the crush washer, I email to tell them and they said they were sorry and would have one out ASAP. Didn't receive anything as of 4/4, so I emailed them again to tell them that I still haven't received anything, with no reply and as if 4/9 still nothing. Really can't use the muzzle brake with out the washer. Great customer service!
