Purchased new as a stripped lower. In excellent condition, has seen 100 rounds fired; only selling to fund a larger project. Includes Aero Precision 6 position mil-spec receiver extension, buffer spring, buffer, buffer retainer, buffer retainer spring, end plate, and castle nut. Nothing has been torqued down or staked. Everything is Aero Precision. $100 face to face in Manheim, PA provided buyer has BOTH a PA photo ID and PA LTCF. If you don't have both of those it will need to be transferred at a nearby FFL at buyers expense. I can also ship to buyer's FFL at buyers expense.
