I've got a couple of non-attached 14.5" barrels from my old defunct gun shop left over, and I'm in the process of building up some AR-15's.
Are those 14.5" barrels legal to use on a non SBR if you attach a flash suppressor that extends them to 16" overall?
Does the flash suppressor have to be PERMANENTLY fitted (tack welded) or do you use just do it normally, with crush washer(s)?
