If theres no other answer than the above then fine, just interested if theres some thoughts on how it could be done differently.

You can increase the dead space in front of the piston by drilling a hole in the piston face but it's a bit radical. Getting a different spring is the easier and more reversible option. You are talking about adjusting the power of the rifle rather than detuning it really, which is what you will need to do everytime the spring needs replacing anyways.
