Thinking about getting a 16" barrel with a profile that ends up with .75" at the muzzle end so that a FSB can be positioned there (at rifle length) and pinned.
Would this barrel profile be considered a "standard"? Any suggestions on top picks or sources for such a barrel? (The barrel would be used to make a mid-length gas dissy upper).
Anyone know of any FSBs made to fit smaller diameter than .75"? Something that could mount at the end of a smaller diameter barrel?
