I have a new in box polymer 80 AR15 80% lower $45 shipped. It does have the metal tab for a serial number.
The Polymer80 80% lower receiver kit contains everything you need to start your next build. Lower receiver is constructed from a single block of proprietary polymer composite with a solid core design, stiffened magwell and beefier buffer tube housing. These lower receivers are 80% finished and require final milling of the fire control group, trigger pin, hammer pin, trigger slot, and safety selector. The included jig system provides an insert for trigger hole drilling, and also includes the necessary drill bits plus end mill bit to finish your lower. Because the receiver is incomplete, an FFL is not required for purchase.
Kit Includes: AR-15 80% Lower, Set Screw Bolt Catch Pin, Dowel Pin for Bolt Catch, Pistol Grip Nut, Pistol Grip Screw, Allen Wrench, AR-15 Jig, End Mill for fire control pocket, Drill Bit for safety selector, Drill Bit for trigger & hammer pin holes, Drill Bit for pin holes & trigger hole. Jig screws are not included.
