Nib. Wanting 16 inch upper in same condition. Or will sell outright. Is registered as other. FTf with Indiana ID and signed receipt.
FYI. Before Delaware machine went bankrupt they made receivers for Sharpes and rguns. This one is I believe the 3rd or 4th variation of markings there is also a rguns version that is marked on the right side. These are mil spec receivers.
Update I have a lower parts kit installed with tapco t6 buttstock.
