I got this as part of a package deal and have no use for it.
It is used, does not look to have many rounds through it as it does not have a lot of wear, Some of the parkerixing has come off the threads where the barrel nut goes but that is common once barreled.
I will also be including a NEW barrel nut with the upper.
Just a note, the park off the threads is purely comedic I put a barrel in to check that it held firm and it was rock solid.
For an extra $5.00 ill include a dust cover
