Here is my question, does Adco make spacers for the KAC NT4? Need to use one a 14.5" barrel to bring it up to 16". If ya all do how much is one with a perm attach?
Yeah we can do that, Just put a note in the coment Section that you need a spacer to bring it up to length, and that you were quoted $25. The perm attach costs $40.
Our spacers are precision ground flat. no different than the shims included with AAC + SF supp. mounts.
wouldn't a better option be a 14.7 barrel with the NT4 flash hider, if this comes out to > 16 inches? Just curious and planning a new upper build
yes, that would be the "ideal" way to go, but you dont see to many 14.7" barrels. 14.5" are extremely common.
