The M-16 has been the primary infantry rifle of the United States military since the 1960s. It is in use by 15 NATO countries and has been the most-produced firearm in its caliber. You fathers out there who have served will remember this one well. Our wooden version slings the rubber bands with force. The scope and sling add to its already great looks. A 12-shot semi-automatic trigger mechanism fires rubber bands as fast as you can pull the trigger. Watch out tin cans!
