Used the 16in Barrel paired with the FM 9mm Muzzle Brake on ar9 carbine build, have taken it out and tested it on three separate occasions and have shot it at 25, 70 and 100 yards with a variety of different bullet weights ranging from 115 to 147 grains & the barrel handled the different bullet weights great - now keep in mind that I have not done any serious target shooting and have been just plinking at cans, bottles and random objects but all the shots have been right in there - so you can tell that it has potential - as far as different bullet weights it seems to really like the 115 GR FMJ the best

the fit, finish price and function are all I was looking for at the time. fits snug in the upper, rounds cycle through my glock style gun just great, no issues with the feed ramp style. I can mostly hit soda cans at my "rapid fire" pace, at 100 y6ards or so. lol. Now I find out that a large part of the industry has moved from the 1/2x36 tpi muzzle threads to 1/2x28. this means the selection of muzzle devices is quite a bit smaller. I will be buying a 9mm gun muffler and trying to find the qd mount I prefer is disapointing.
