I did a search but couldn’t really find anything

Question is on the later type HW45 Air pistols they have a two stage cocking for different power this got me thinking about if this can be implemented in a Springer Rifle?

I’m not quite sure how this works on the 45 I assume it’s to do with piston travel and varying pressure on the spring.

For example let’s take a smallish type rifle say the HW99 would it be possible to modify this so a half cock would have less pressure and obviously a full cock would give it the full power?

I’m thinking this would be ace for juniors as they could grow with the rifle and also offer seniors the choice of low power plinking or close range work if required etc

Dunno just one of those quirky brain moments that’s probably been answered many times before
