I put a Bushnell Trophy XLT 4-12 with AO on my RWS 54. At over 1000 rounds, it's still holding up, as it should since it's airgun rated. I got mine from Amazon for less than $140, but currently it's $199.95.
Both of my sons have had this scope or its predecessor on .22s with good results. One still has his and it's going on 20 years old.
