OK, trying the Weaver Classic 3x9 on my Hatsam .30, with the RWS "Lock Down"mount. Have it "sighted in", & zero problems SO FAR. Also trying a Bushnell Bammer 3x9 & a Mizugiwa mount (similar to the RWS) on a Bemjamim Prowler .177 break barrel. Both of these scopes were purchased "unused" from folks who wanted "better" optics for centerfire rifles, so they were priced attractively. If they hold up, the mounts will make them good choices for my air rifle use.

I'll report back after more shots have been fired, to see how they work out.
