I have a registered lower that I plan on pairing with a 10.5" barreled upper after I chop the barrel down from 16" and adding a sba3 brace. The uppers barrel is a carbine length gas, 1:7 twist with a standard ar bcg.
My question is that of buffer, spring, and gas block selection as I'm a little unsure of what I should look at first. I do want to run super and subs through both suppressed and unsuppressed. I'd rather not have to buy another barrel as it came with the complete upper assambly.
