I want to buy a deregistered 6921with a pinned FH from Knesek guns. It appears to be the closest to NFA 6921 the way they pinned the FH. Anyone have one and what do you think?

I had one that was built with a KAC gas block sight and a URX rail with a pinned KAC QD FH.


Colt is the gold standard but you can get an equal quality upper from someone else for less...or still a 14.5" but with a different (better) profile like Noveske. If you just want a "Colt M4" then the 6921 upper is what to get.
