I have a Saiga 12 that I purchased back in November and I've been having problems with FTE. I've tried different types of ammo, put a reliability kit in from Carolina Shooters (MD Arms) supply but still having problems. I change out the gas puck, gas selector and the spring. I spoke with R & R as the specialize in Saiga 12s and he recommended a complete take down, inspection and polishing of all the parts (if needed). I've hear good things about them but wanted first hand info.
