The Daniel Defense Extended Flash Suppressor has been permanently pinned and welded to the barrel to bring it to the required 16" minimum and keep the rifle safely out of NFA territory.

Can't go wrong with the DD M4A1 and Primary Arms is the place to go.

Daniel Defense M4A1


This is a fantastic package. Everything is mil-spec+. My only small complaint is that the trigger pull is gritty. Not heavy, this is after all a duty gun, but very inconsistent pull with a dirty break. I am going to put a few hundred rounds through it and see if the condition improves or it will need to be serviced.The quality of materials is very good and overall I am very satisfied with the firearm.
