You could buy a Diana mount

It is likely less expensive overall just to purchase a springer-classed scope, than the Diana model.

However, any time there are moving parts, there are contact part tolerances.

Bit of a price difference, there.
Might help, indeed. However, any time there are moving parts, there are contact part tolerances.
At typical air gun range of less than 100yards, perhaps the fact there are moving parts will not
effect accuracy enough to matter.

You've likely heard that springers have 2 recoil pulses. That means the scope tries to recoil/slide forwards (as the spring slams forward), but also backwards as the piston stops.

Scopes designed for springers are designed to prevent damage from those double-whammy recoil impulses - forwards and backwards, whereas PB rifle scopes are designed for resist damage from only the first scope impulse, to move forwards.

IN springers, the stopping of the piston is the stronger impulse, as well. The scope in a PB gun will try to move forwards in the rings as the rifle recoils back. The springer's scope will try to move backwards as the pistol slams to a halt and the gun recoils forwards. What we usually feel is simple vibration pulse.

PCP rifles produce the same style of recoil that is produced by powder burners.

The recoil of some of the springers is strong enough, to destroy even scopes designed for them, even the more expensive of them, let alone the less expensive versions.
