I've been looking for an adjustable gas block for a suppressed DPMS 308. Barrel is .922 in front of the original.
May I have a little help on what I "should" be looking for. I found .875, .750.
I'm missing something???
Today I received a check in the mail from NFA. It says application refund on it. Everything looks real on it, no letter, explanation or anything. Anybody else???
