AR-15 Lower Parts Kit (LPK), 31 pcs.

These are Mil-spec kits we buy from an OEM manufacturer that sells us contract over runs. Thus sometimes we have them, sometimes we don’t.

Comes with all 31 pieces required to complete a standard AR-15 lower receiver. These are every part you need to complete your lower except for the recoil system – buffer, buffer tube, recoil spring etc.
