The Army shows off its latest breaching weapon: the M26 Modular Accessory Shotgun System during a test shoot at Aberdeen Proving Ground. The M26 Modular Accessory Shotgun System (MASS) is a developmental under-barrel shotgun attachment for the M16/M4 family of United States military firearms. It can also be fitted with a pistol grip and collapsible buttstock to act as a stand-alone weapon.
