Billet Ar15 receiver set (in state prior to ban) near South coast, Massachusetts, USA

Specialized dynamics billet ar15 receiver set (upper and lower). Low serial number. Was registered in state as a complete rifle.

Will come as a complete lower minus stock. Upper only (no barrel, bcg, charging handle, or rail)

these are hard to come by. Beautiful receiver set, just thinning my collection.

open to partial trades.
