This is a new CMT upper receiver with a used, excellent condition, converted postban Bushmaster 1/9 barrel that was turned down by KKF. I received the barrel in trade and it was reported as a low round count barrel. The bore, chamber, throat and rifling all prove it to be low round count.
The barrel is stamped "B MP 5.56 NATO 1/9 HBAR", but as you can see, it isn't an HBAR.
Assembled by me and test fired only (for function - not sighted in).
Offered as pictured, without
bolt, carrier or charging handle.ASKING $275
Payment by USPS MO only.
