The euro 20mm guns of WWII that were going for a hundred or two back in the 1960s weighed 100lb, not 50lb. And they could move a prone shooter backwards IIRC.
Remember Col. Dilger ?He had the armorers at his Air National Guard base in VA make a 30 mm single shot rifle out of A10 Warthog parts.He was transporting it loaded and it went off, bending his pick-up truck in half.I wonder how many more of them are out there?
"Some Allied infantrymen mistakenly assumed that the launcher's curved plate was propped on the leg to fire and thereafter referred to it as a "knee mortar". However, any soldier or marine who tried to fire a captured Type 89 in this fashion received a severe bruise (and sometimes a broken thigh bone) from the hefty recoil."
I think you can rest assured that some fool will try to fire this 20mm Vulcan "destructive device" dismounted from that tripod with not so good results.
You see, there once was this guy named Charles Darwin........
To "FedUP" above, A muzzle brake tames the recoil just fine. I've fired a 20mm Lahti and it won't move a shooter backwards, nor will it "bend a pickup truck" from another post up there. Rolls eyes.
There are plenty of tube videos of people firing 20mm stuff. The muzzle blast is worse than the recoil and that is only felt if you are standing right or left of the shooter.
If this fool had any idea of how susceptible those 20MM rounds are to going off due to static electricity or EM (radar), he would probably crap his pants.
Gee anon @10;05nothing about this post has to do with Sweedish 20 mm loads.A 30 mm D.U. round has nearly double the powder load of any 20 mm you ever shouldered.If you bothered to google Col. Dilger the accompanying photographs would show you a completely inoperable vehicle!Your grasp of english is lacking.Let me explain.The rifle we're talking about was unsecured in the bed of a truck and went off.Therfor it tried to go in both directions.The only thing stopping that was some Ford sheetmetal.Thus endeth the lesson ...
Meh, pants crapping is a hazard of life for the elderly, just wear the appropriate undergarment. I'd guess the guy leaves them in the belt for just that reason. He seems capable of figuring out how to set them off, and he apparently didn't do so by trial and error.
A 30mm GAU-8 is a completely different beast from a Lahti, just like ceramic/DU composite is different from steel-plate. Those 20mm cannon rounds are much smaller, but they're still not the same as what the Lahti fires.
And if you didn't move...well, I'll not get personal about it. Some full-grown shooters can't fully stabilize a Lahti, and the platform is designed to accommodate them.
Still, all and all, I'm not going to try this at home.

Sweet! Just gotta get the recoil under control!

Remember the Japanese Type 89 "knee mortar"?

Which parts of this thing are NFA?
Ave Nex Alea.
If you don't know what that means, that's okay. You're prolly better off.
"The rounds are inert", until you fire, at which point they are inertial.

To Bohunk^^^^^^^The bore of the rifle being 20mm classifies it as a DD according to ATF regs.
Anything over .50 caliber (excluding smooth bore shotguns)are considered destructive devices and must be registered with, and tax payed to the ATF.
