I am torn between 10.5 and 12.5 inch barrels. I like the look of the 10.5 much better, and thats 2 more inches of maneuverability.
The rifle will be a Noveske, and I trust that since they have a video of a 10.5 dumping 3 beta-C's since half a decade ago, they know how to make one run, as well as a 12.5.
My question is: I don't want to run a brake. I really just don't. It's obnoxious as hell without a suppressor, and while this is a dedicated suppressor gun, I may at some point want to shoot it without one. I would like to do that with a flash-hider.
Will the 10.5" eat a blast-baffle exponentially quicker than a 12.5"?
Will the 12.5" stabilize rounds a lot better than the 10.5"? I mean, if it will cut my chances of a baffle-strike in half, I'm all for it, but if it reduces them by 1% or something, well, whatever. I want to be able to shoot 70gr TSX or 77gr MK262 without fear.
I am going to be running a Surefire 556-212 suppressor. Assuming I use a 212A flash-hider (the one that looks like a big A2 kindof), will shooting the weapon be nearly negligent in the damage it causes to the suppressor, or will I just cut a 30,000 round service-life down to say, 20,000 rounds (arbitrary numbers). I don't plan on back to back mag-dumps and I don't have an RDIAS. Firing schedule would be, at the "worst", similar to a carbine course following range-commands (i.e. not dumping a Beta-mag into the berm showing off or whatnot).
Also, is there a point to a Switchblock on a 10.5 or 12.5" rifle, or is it going to be dirty as hell and blow-back in my face like crazy no-matter what? Do they blow-back at noticeably without the switchblock in SBR configuration, or not like a longer barrel (I know it's going to get dirty regardless, I am mainly concerned with blow-back and reliability both suppressed, and un-suppressed)?
Further, I am worried about the suppressor mount coming loose. Noveske is building the gun, so I know it will be torqued to spec and Rockset used. However, is this one of those "you really need to keep an eye on it..." type things, or is it "It's on, now forget about it until you decide to change it. They only come loose when bubbah does 'em in his garage." ? I ask this because I wonder if having whatever I go with pinned is good insurance for my suppressor, or just over-thinking it. I have wondered this ever since a guy had a baffle-strike and posted about it on here due to his suppressor mount coming loose. He attached it--not Noveske).
I know, these are probably something heard often, but after searching I didn't find the answers pro or con that I was after. Please bear with me, I did use the "Search" button on this and other sites (silencertalk).
