You should only install those scopes specifically made for air rifles. A standard high power rifle scope will not stand up to the double recoil of an air gun. The glass mounting rings in the standard scope are designed to withstand one-way recoil, not the two-way of a spring actuated air gun.

Check the Bushnell catalog for air rifle scopes and choose one of those.

Agree with Kdub...have had air guns "eat" good centerfire scopes (at least the spring airs...the pneumatics, recoiless spring airs, and CO2's just don't cause any problems).

Problem is that the gun actually recoils a bit FORWARD as the spring piston comes to a halt and then actually bounces back off the lump of compressed air it creates...then pushes forward to the end of the cylinder. Hard to notice when you are shooting it, but if you stand off a bit to the side and look hard at the muzzle while someone else shoots, you can see it do that backards-forwards-backwards dance.

How bad is it...well, if your scope mount isn't on tight, the mount will walk off the BACk of the rifle. IF it were striaght recoil (as in a centerfire), it would walk off forward as the rifle recoiled out from under it.

So...scopes made for regual recoil have the internal parts braced for one-direction recoil, not for that two-direction vibration. Things loosen up fast unless the scope is made for it.

On really light recoiling spring airs, non-airgun scopes can live for a good long while...as spring power goes up, their life span gets shorter.

Make sure you use proper mounts too. My RWS Air rifle made me nearly eat a scope once. I tried to save money and go with cheap Wally world rings and base...no can do...

Thanks guys but my research shows that the trophy IS rated for springers.
