Mr. Churchill's favorite gun


During the period of 1979 - 1990 an American by the name of Jeff Caselman developed a weapon which was, and still is, revolutionary in concept and design…..the worlds first Air Powered Self Sufficient Machine Gun!

As Jeff himself wrote "with gun prohibition perhaps staring us in the face it is nice to know you do not have to be without protection. This gun was designed with the idea that any and all guns could be banned and ammo could be illegal or unavailable, this is why we strongly urge you to have these plans. To have the security of knowing you can make a high powered automatic weapon using high pressure air………..a self sufficient alternative for home protection and defense, and also the inexpensive pleasure of machine gun shooting."

The machine gun is a basic blow back system designed to operate from a pre-pumped detachable tank of approximately 100cu in capacity, which also acts as the stock. The weapon can be extremely powerful for 30 shots or tuned down to 150 shots for fun shooting. The gun uses a cast 1 in 40 parts tin/lead bullet and will saw a 4" x 2" in half at 25 yards!! No cases, primers, or gunpowder………… and no forensic evidence!

After developing this amazing weapon Jeff Caselman mysteriously disappeared. He just vanished without a trace. Some say he emigrated to become a missionary in the Middle East, others, that he was "taken out" by a hitman hired by a conglomerate of American ammunition manufacturers, and even a rumor circulated amongst those "in the know" that he went to England and joined forces with the 'Homegunsmith' to perfect his design and now lives in a secret underground arms manufacturing facility beneath a hop field in south west Kent.

As a tribute to Jeff Caselman the complete construction plans for this amazing weapon are available here.

I am indebted to my good friend Mad Abe, a former "Soldier of Fortune" turned author (see who patiently endured 15 years of searching to track down the plans which are now shown here for the first time in their entirety.

These plans are available from no other source. While I do not usually supply firearm design plans written by others, the design of this weapon is so unique that they deserve a place here.
