current set up is a minimag with nothing special--had a slight leak when I got it but thanks to this forum I got the idea to replace a few o-rings and put oil in it and the leak down the barrel stopped. I then got a intelliframe and instant crazy leaks. now it is leaking out the back and down the barrel. I put new a new reg seat oring in and that did not help. I got it used and it had not been used in a while so is it possible I just need the reg rebuilt?
