Anyone knows what these are?
The mag measures about 129mm, they look like old style sv mags to me, but I am not sure. no markings anywhere.
The basepad looks like dawson to me, but it's different from all current ones. The locking groove are on the top rather than at bottom. it adds about 13mm and that makes the overall length just little over the limit, and it doesn't fit the gauge:-(
How can I make these work?
