• Includes a Picatinny Rail on the bottom rear of the Stock Body to attach your choice of many accessories.

• Certain after Market Commercial Buffer Tubes that exceed  1.172″ diameter, may not fit

Additional Information

The MBA-3 does not include the following accessories, they can be purchased separately:

• Sling Swivels (Side or Rear)
• Carbine Buffer tube
• Carbine Buffer Body
• Carbine Buffer Spring
• Latch Plate
• Lock Ring

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.
