So I am getting the rest of the parts I need for my suppressed SBR 9mm AR build. I understand there can be a lot of gas coming the shooters way. I have been looking at charging handles. The PRI Gasbuster seems to be the one a lot of people use. I have read on other fora that the VLTOR/BCM charging handles seem to work at least as well, especially if you dremel out a notch on the right side of the handle. I already got the 9mm-Q buffer with the Wolf XP spring, and that is supposed to make a difference. There is also the silicone trick (which I would like to avoid). Does anyone have any experience with this kind of set-up they would be willing to share?
