I have a colt preban hbar complete upper. Includes these features: 1) small hole 2) no bayonet lug 3) A2 flash suppressor 4) A2 sights 5) bolt and bolt carrier 6) charging handle.
100% Colt. This upper came this way from the factory. Has about 200 rounds through it. I switched uppers and is why I am selling this. It is in excellent shape. I give 3 day inspection and full money back guarantee less shipping costs. Sorry, no pictures. Price is $423 shipped.
Bonus - I purchased from ebay a front sight assembly with bayonet lug for this gun. I will include this for no additional charge.
PS- This is a heavy barrel upper. It came from a blue label model #6601 purchased new by me.
