The world moves on - FM Products Foxtrot Mike Ultralight 41V50 9mm AR Barrel

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.
