I'm sure you have shot it after installing the compensator, how big of a difference did it make?
Oddly enough, I don't know....yet.
I put it on 2 years ago and never made it back out to the rifle range to test it. I should've though, because there could be a point of impact difference.
Not highly likely, because of my experience with my 243, which never changed anything....just projected the sound away from me.
I will shoot it before the end of the Deer Gun Season.....if for no other reason, but to hear it.
