I've got a 16" upper with 0 rds fired.
Ii's a flat top with no Fwd Assist.
The bolt and carrier group is different for an upper w/no fed assist.
It has no milled serrations on the right hand side.
I bought an extra upper w/ fwd assist and a 20" barrel assy with the intention of building the 20" upper I wanted. Cash has been a problem.
Does your trade offer include the bolt and carrier group for the upper w/ fwd asist?
