Been using a pri gas buster for years with all my aac suppressors and today I have had enough of the blowback. Anybody try anything else to seal up the gap that the gas buster leaves. Could be that crappy monarch academy stuff I was shooting but it was damn near unbearable today. Ive heard of using sealants and o-rings but I want to see if some others have tried to fix this problem. So chime in with some ideas.
