No problems. Attached to a aero m4e upper with a 16.6 hand guard. The break on the suppressor just stick out enough to get enough hand on it to put on and take off
Would you recommend this? Yes, I would recommend to a friend

Run a can
Mine runs very good with subs and supers with a medium to high back pressure can, BUT it is on the very edge of running reliably with subs when using a lower back pressure silencer. If I step up to a heavy recoil spring it will not lock back on an empty mag, or will short stroke depending on ammo/can combo. In my opinion its better than being over gassed, but I would be surprised if it ran anything other than hot supers w/o a can. It seems to be relatively accurate.

A little extra work
Barrel doesnt come pre dimpled. The cut for the gas port also had some burrs that prevented the gas block from smoothly sliding on and had to be smoothed off.
