It may also be worth taking the recoil spring out and cleaning out the tube and spring. Mine had cosmoline down in there and caused the recoil spring to be sluggish at times. If your gun worked fine before the dsa scope mount and mags, I'd see if using the old mags or removing the scope mount causes the jamming to stop. Then you can track down why its happening. Like Allesennogwat also mentioned, properly adjust the gas system.
