Well from what i can see on these rifles the company that did this reshaped the military stocks added crude cheakering an pistol cap along with flat rubber cut to shape butt plate.
the cleaning rod hole along with swivel holes were plugged an then stained black. they all have same import mark near muzzle end. Might have been the importer who did this or exporter.
Will find out how they sell this week end at the Scranton Pa gun show. got them priced from 200.00 down
