went to gun show sat., bought an ATI folding stock for my sks. stock fit ok with a little trimming where the clip goes in. bought a 20 rnd clip but had a hard time getting the clip to engage and disengage. anyone had the same prob.? the clip jams regular and does not raise the incoming cartridge high enough to clear the chamber opening. any help? roytinman on gcgf or roytinman@gmail.com.
