Installation Notes:  

• When tightening the anti-rattle set screw, be careful not to over tighten as the threaded insert may separate from the plastic stock body
• When sliding the buttstock onto a 6-position buffer tube, the lock pin has a notch in the head of the lock pin that must line up with a tab on the stock body. Once the slot and tab are lined up, the pin can be fully retracted allowing the buttstock to slide onto the tube. The MBA-3 should slide easily without resistance. If there is any resistance, the lock pin is not fully retracted.
