Judgment Arms M1A1 M.A.W. 2 inch Shoulder Cannon, a First and a Last:
First things first, the technical data:
Caliber: 2inch, 50mm (2”X10”R M2 cannon cartridge)
Barrel length: 26 inches, 660mm, 13calibers
Reservoir: 2”X17” 53.4in3, 50X431.8mm
Muzzle velocity at 100psi: 220fps, 67m/s*
Muzzle energy at 100psi: 141ft*lb, 191.3J*
*according to the GGDT
Valve: unmodified “Frankenstein**” 1” sprinkler valve
Now let me explain what I mean by “a first and a last”:
Firsts:
1. “successful” use of cartridges.
2. “man portable” air cannon.
3. modular cannon (explained latter)
Lasts:
1. attempt at a man portable air canon that uses low pressure high volume (LPHV)
2. using a 1” sprinkler valve as a main valve
This cannon was designed to be a man portable grenade launcher, but this sucker is HEAVY. At 12lb this thing is definitely not a L.A.W. (Light anti-armor weapon), meaning the designation of MAW, or Multipurpose Assault Weapon, is more like Massive Assault Weapon.
The good news is that it works exactly as it should, besides being heavy, it’s about what I was gunning for.
Note the designation “M1A1” for those of you that don’t know, the A1 designation means this ain’t the original, its bean modified, a lot…
The original didn’t have a stock just pipe and no breach plug, the thinking was that the cartridge would throw itself out and still have enough power to put paint and NERFs down range at 230fps, obviously it didn’t work.
A1 version adds a plywood receiver, a pine wood stock and pistol grip (modeled from a Colt SAA grip frame), and a breach plate
On the muzzle there’s a 2” female threaded adapter, to which will attach some planed accessories, including: a bipod, 20” barrel extension turning it into a mortar, a choke for shot, and a 3”X12” barrel extension for larger projectiles.
*the valve is made from a conglomeration of 3 or 4 different valves because none of them worked as a whole; they all sounded like angry wookies.
Range Data will be added as I get some, questions, comment, criticism are welcome.
Here’s some photographs of the cannon and the GGDT data on it:
