I recently got a new reg that will let me increase the output(at 920 right now) and when I hooked it up to my minimag(stock as far as I know) I actually got a little bit of bounce. I can get another kit to further increase the output on the reg but wonder if it is worth it. I got the mag as a free fixer upper and I replaced all the o-rings and got a spacer kit to fix a leak but don't know much about it beyond that.
