Watch the belt-fed 12 gauge you need to see in action (VIDEO)

What you are about to see is a prototype of the belt-fed 12 gauge upper receiver in action. The video, which was posted to YouTube in 2009 has garnered roughly 1.7 million views with mostly positive feedback.

This gun uses your lower receiver, so if you have an AR15, its a semi-automatic shotgun. However, if you have a registered m16 lower receiver or a drop in auto sear it becomes a full auto 12 gauge machine gun.

Even though this belt-fed 12 gauge upper receiver is amazing, there are a few problems with it. The person who created the video said he was having trouble getting the shotgun shells to eject from time to time.

This is evident in the video as he consistently has to fix the issue while firing. While this is not the ideal firearm to have in life or death situation, it still is an extremely interesting and fun weapon to fire while at home or at a range.

As can be seen in the video, there is a lot of kickback, so the belt-fed 12 gauge upper receiver needed to be stabilized on a wooden platform.

The short-barreled gun, which has a home-made upper receiver and an AR-15 rifle lower receiver can fire both automatic and semiautomatic 12 gauge ammunition, may be too short to be leal as the barrel does not reach the mandated 18-inch length.

In the United States, it is illegal for a private citizen to possess a shotgun with a barrel length shorter than 18 inches or a shotgun with an overall length of fewer than 26 inches without a tax-paid registration from the Bureau of Alcohol, Tobacco, Firearms and Explosives. In the past eight years, the YouTube channel that uploaded the video has yet to release a new video. It is possible that because the shotgun has a short barrel that the Bureau of Alcohol, Tobacco and Firearms may have done something that way he couldn’t possess the shotgun anymore.

What would you call this thing other than a light machine-shot-gun? (Make sure you swap the barrels out to keep anyone without a sense of humor happy).

Like any “because you can” weapon, the belt-fed 12 gauge is a special kind of crazy, the kind you want in your collection. This custom upper receiver can be attached to an AR-15, but you won’t find it in stores anytime soon.

While there are a few malfunctions, the “jam” appears to be spent casings failing to clear the bolt. Fix the jamming issue and you have the greatest home defense weapon ever.
