Installation Notes:  

  • When tightening the anti rattle set screw, be careful not to over tighten as it may cause the threaded insert to separate from the plastic stock body. 
  •  When sliding on 6-position tube, the lock pin has a notch in the head of the lock pin that will line up with the stock body. This needs to be lined up before sliding on the tube. The tube will slide on easily without resistance. If there is any resistance, that lock pin is not in its place.
