Springer scope twang

[Oly1]

I recently tuned my springer but found that a large amount of the twang heard on firing was the internal spring of the scope.

I read that this is a spring built in scopes (particularly with AO?) to deal with the recoil from spring air rifles.

So which scopes are better/worse (bearing in mind its still got to withstands springer recoil)?

Are there any features that minimise/remove scope twang? Are side parallax scopes better?

Is there anything you can do with existing scopes to reduce twang?
