Got one in my M4 at the moment, haven't had chance to shoot it yet but the barrel cosmetically appears perfect.

Got one in my TM M4 not bad I might say myself not had any issues so far but if I am honest the amount of different AEGs I have it only gets used here and there so couldn't say what it's long term performance is like.

ok great cheers does it seems to have given an increase in performance? or any noticeable?
