bought a used Logun MKii last week and had a very poor days shooting Sunday. looking for guidance on remedial action before sending back to Logun for overhaul.
Gun loads pellets faultlessly but frequently fails to charge with air...wont fire. Have to unload magazine to avoid double feed.
Gun intermittently fires when cocking which discharges pellet.. not funny.
Gun will not now charge with air. will not dryfire.

Anyone with any bright ideas??
