masonuspsa1 Posted September 8, 2022 Share Posted September 8, 2022 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?

ogiebb Posted September 8, 2022 Share Posted September 8, 2022 yep old SV mag tube with a Dawson plus 2 basepad (discontinued) you can change the basepad to something smaller or shave the bottom of pad / back of feedlips. Quote Link to comment Share on other sites More sharing options...
Grendel Posted September 8, 2022 Share Posted September 8, 2022 (edited) You can use the Grams 11mm base pad - they look great on it as well .. Edited September 8, 2022 by Grendel Edited for picture Quote Link to comment Share on other sites More sharing options...

masonuspsa1 Posted September 8, 2022 Author Share Posted September 8, 2022 ogiebb, were these base pads supposed to be used with 126mm base pads? Quote Link to comment Share on other sites More sharing options...
