Ive actually cut out a few and compared them to non-cut chamers. It for sure does not hurt, but as for gain, I believe there to be a SLIGHT, and I mean within a few inches, of range gain.
Thanks for the input.
Oh well, I guess ill just have to live with the AR in, since I REALLY don't want to open it up.
One more question though, whats the word on peg removal on the chains? Does it increase/effect range at all with stock darts?
