Lightly used 8/10 condition lower with installed takedown pins, mag release, receiver extension (buffer tube), PWS ratcheting castle nut w/ qd endplate ($40 value), buffer retainer pin, spring co blue or red spring (your choice), H0, H1, H2, or H3 buffer (your choice), and a Phase 5 extended bolt release v3 (basically a BAD lever but a single piece of metal - $53 value). Basically all you need to complete the lower is a trigger, grip, and safety. If you have any questions, don't hesitate to ask.
