PWS 7.62 x 39 upper receiver, can use for an SBR or AR pistols. Fewer than 500 rounds through this upper. Has a 7.5 inch barrell, so it can only be used on an AR pistol or registered SBR. Includes magpul back up sights front and rear.
I also have several 7.62 x 39 AR magazines for sale at $10 each.
