I apologize in advance for the poor picture quality. I can attempt others if you need them...
Remaining is a 16" flat top upper with a Miculek comp attached. It comes with a 4 rail gas block and free float YHM 4 rail hand guards.
SPF shipped (OBO) with a charging handle....or $SPF
with bolt & carrier.
This was assembled by DPMS. I don't believe the barrel is chrome lined. It is labeled DPMS CAL 5.56 1-9.
Will take MO or Paypal (+4%).
Thanks for looking!
