I think the barrel should be all the way back when the bolt opens.

it uses short recoil operation like a Luger or a Pederson.

2 things: the rounds have a horribly messed up force (make it much lower and more constant) and notarget is right, the barrel should be linked until all the way back

it operates on the SHORT RECOIL principle, where the barrel moves only enough to unlock the bolt. its similar to the difference between a long and short strock gas system. look up how a barrett m82 functions and you will see that short recoil operation is a thing! does the luger's barrel move the entire length of the gun? no, it doesn't. please get your facts streight before you bash my scene.

Toggle action, only ever seen that on a Luger.
