Worth mentioning the Armbrust:Who knows i might try the counter weight method. And yes water (possibly with salt) has also crossed my mind, just need way to contain it but that's the least of my worries for now

It will still be disproportionate to the amount of gas you need to balance out the recoil - rule of thumb with recoilless guns is about only 20% of the propellant pushes out the projectile, the rest is countering the recoil. I don't think it's worth the waste really.What about using high pressures? Or actually narrowing the nozzle to create more back pressure? More like a Laval nozzle rather then the Gustav's "venturi" nozzle? Like adding a union fitting at the back and using washers with different sized holes until you find a sweet spot?

Hah! I remember that thing, high impulse weapon something, from France if i remember correctly. You forgot the second part where the other guy got his ass kicked by that thing! Not exactly low recoil tho :p I had been thinking of building a stock from an old pneumatic cylinder to absorb some of the kick. All made the thing a lot more bulky and heavy tho, which i guess also helps with recoil, but i'm not Joerg SpraveI think it's a better idea to incorporate a system that spreads the recoil, ie allowing the barrel some dampened movement on a fixed mount, something like this:
How would all the air not just simply escape from the back instead of pushing the projectile out? Your design is kinda what i had in mind with the counterweight, but the green arrow would be where the weight was sitting and the projectile would be in the longer barrel. I guess i could use a bag of water as a counter weight to reduce the risks of damaging something or someone standing behind it.Here is another suggestion (blue arrow up, green arrow towards target):
This option lacks the drawbacks of already stated options:
1/ Nobody behind you will get blast of gases as in second option, or get hit by an object twice the mass of your bullet as in fist option
2/ It will be much easier to make (standard plumbing equipment), easier to clean (if joints are threaded) and less likely to suffer permanent damage than Spagin
Otherwise it will keep the benefits of Spagin, preventing both recoil and muzzle jumping up. The pinhole may or may not be required however it will make it less likely you will shoot the whole appendix off.
