While I wait on the paperwork to come in, are there other things that need to be done to have my firearm suppressor ready? I've been reading around the forum and have noticed a lot of talk on adjustable gas blocks and suppressor usage. From what I've read, I'm guessin' I need to get some form of low profile adjustable gas block for my rifles (the can is going to be shared between my 6.8 and 5.56 sbr). Any recommendations on what I need to get? If anything.
