I have a good condition MandA parts 10.25" upper for sale. This particular upper has about 350 rounds through it, with small mounting marks on the carry handle from attaching gooseneck Aimpoint mount, small rub mark under front mounting pin hole, dings on brass deflector and small brass marks from removing front sight base (was gonna replace it with a no-bayonet lug version, but it didn't fit).
Threaded barrel, no flash suppressor (I'll throw one in, I just don't feel like going out to the shed in the snow and mounting it), no bolt, carrier, or charging handle.
This is a great place to start for a pistol build or an SBR project.
This unit has run great, with NO FAILURES! I am confident that you will be satisfied with it.
Mand A lists these at $320 (although for some reason 10.25" is no longer on their website)
Will sell for $250 shipped in the lower 48. Prefer USPS money order, checks will need clearance time.
Email or IM me.
Have pics for interested parties, I just can't upload them, they take all day, cuz I live on the 56k dirtroads of the information superhighway.
