These with the vertical slide serrations are made from recycled military Type 54 parts and take full width mags that have a spacer riveted to the back.

This one has matching serial numbers and comes with a 2nd nonmatching mag and a pair of surplus Type 54 grips.

Price is $350 or trade for a sporterized M1903/A3 I can use for a build I’m planning. I’d like the buyer to have a carry permit or something.
