It works by pulling the shutter back, pressing on the lever and pulling the upper part of the shutter, which should be connected to a large spring as resistance.

And by changing some of the shapes you can change the mechanical advantage in how fast the upper part (bolt carrier) moves aft versus the receiver.

Yes, it is possible to change the movement time of the upper part of the bolt and thus the speed of the cartridge case extraction by changing the shape.

The guys at the RPF need to see that.
