The M40 is the United Marine Corps standard precision and tactical rifle or most often referred to as 'Sniper' rifle. It's a heavily modified military-type version of the Remington 700. Pictured above is the M40A3. This M40 Sniper Rifle papercraft comes in its basic OD green color, I would have preferred a camouflaged one.
