Look at this baby - a 37mm round necked down to 20mm.
The russian RES 4 AT rifle - may be somebody knows more ??
There is an 14,5mm BNS too.
Auch !!..that is awesome. The muzzle velocity must be kolossal.
Thanks for the pictures.
Tasty !! any more info?
I’d hope the recoil management works on that–otherwise I might lose an arm firing it
There were tripod-mounted 37mm guns used in World War I for close-range action:

I am currently 54 years old and come from a very Gung-ho Marine family. When I was 13 I was given the Marine manual as a birthday present. I very clearly remember the instruction for making the “sticky bomb”. You have to have brass balls to face your fear enough to use that thing. I have great respect for men that could take on a tank like that.
Would the 37/20mm be a recoiless rifle? I see a scooped chute behind the breech, otherwise it would have some kick to it. The 20mm Carl Gustav rifle was recoiless, and used a similarly shaped cartridge.
As far I know wasnt, but the muzzle attachment is a very dedicated muzzle break that reduced felt recoil in 40-50 %.
I bet the ‘RES’ burned out barrels fast. That round is way overbore so the hot gasses would eat the bore up fast.
Better they steal the Gerlich principle, or sabot, or Davis recoiless gun (in fact the Russians did try with the DRP cannon.)

Indeed , the DRP ( dinamic reactive principle) was tested before Ww2 in aircraft armament for the VVS, weirdly wasnt tested for infantry usage.
I disassembled a Chinese version of the Russian RK AT grenade in RVN.
It had a full parachute inside that deployed when you threw it.
You kind of whipped it and the handle came away and the little canopy, about a foot in diameter, popped out like an umbrella.
There was a spring loaded firing pin that set the thing off.
A pretty nutty and dangerous idea, to mee.
