I have one Colt 6450 Upper Receiver Group without bolt group available. Barrel is marked C MP CHROME BORE 9mm.
My SBR paperwork came back on the lower half, so I'm moving the top half to help pay for a 9mm SBR upper.
Does not include bolt group or charging handle. Upper is like new, less than 150 rounds have been put through her.
Price is $400 plus the shipping and insurance of your choice from PA.
