[franks71vw]

So lately i have managed to lose little screws, detent pins, etc and now i have managed to screw up the retaining spring for a saiga 12. I have searched the net and cant seem to find a place to buy a replacement... do any of you guys know where i can buy one from... i am in the middle of the conversion and cant put it back together cause of that spring?
