Ar-9 with two uppers
both uppers fit great with this lower and Stern mag conversion so selling together.
Stern nickel bcg (I'm pretty sure this BCG is not Frt compatible)
comes with a 30 round factory beretta mag
both uppers are NBS pistol uppers with a nice big ejection port.
the 16" has a lead star barrel and NBS rail 1/2 x 28 threading
the 4" has a Stern barrel with 1/2 by 36 threading.
This rifle would be great for a supressor but I wouldn't recommend AR-9's for FRT's due to lack of a locking lug. If you wanted to frt this anyway you would either have to switch out the bcg or mill it out but there is a rabbit hole of what do do with buffer weights and weights that slide back and forth to prevent bolt bounce and hydrolic buffers and roller delay buffers
