I just got a Rimfire-specific 22LR scope from Cabela's. Only tried it today, but it's very clear, holds zero, and the calibrated crosshairs match up to 22 LR pretty well. I don't know what the durability will be like, though. As far as service goes - I got this as a replacement for a BSA scope I bought from an adze-hole here that was defective (the scope, not the adze-hole). I contacted BSA, but their service depot is in the US, and because of ITAR BS, I couldn't get it serviced there. They sent me an E-Mail and told me to go to Cabela's or BPS. So I went to Cabela's, and they gave me this brand-new Cabela's 3-9X40 scope under BSA warranty.
