This upper has had one 30rd mag of American Ealge ammo through it. It has an UNTHREADED muzzle with a Smith muzzle break.
I am moving out of town to where I will be able to carry my AR every day so want a lighter barrel.
I would like to trade for either RRA or Bushmaster upper with an M4 profile barrel. I don't care if it is flat top or A2 sight configuration, also don't really care if it is threaded or unthreaded muzzle though have a slight preferance for 14.5" with welded phantom flash hider.
You can email me at firstname.lastname@example.org, IM me here or call (907) 622-6449
Edited to add, I just took a couple pics of my upper email me if you would like me to send them.
