The Colt Defender Mark I was an American multi-barreled shotgun intended for law enforcement or military use, completed in 1967.
The shotgun was essentially a volley gun with eight single-shot barrels — each chambered for the 20-gauge 3-inch magnum shell — arranged in a octagonal fashion around the central axis, and could fire eight individual times like a Semi-automatic firearm without the complexity of actually being a semi-automatic.
The gun had a detachable buttstock and a pistol grip with a double-action trigger and had a separate foregrip up front for instinctive shooting.
Colt demonstrated the weapon to a number of departments, and all who saw it were impressed with its compactness, volume of fire, and reliability.
The weapon was composed of an aluminum alloy receiver with steel inserts and was covered in an epoxy paint finish.
