All tier 1 gear - Spuhr ISMS 34mm Rifle Scope Mount

Spurh doesn't make anything bad or even medium as far as I know. Everything they make is really good or fantastic. The owner designs the stuff and he's a very creative engineer. For example, on the various attachments you can get to put on a mount, extra pic rail or whatever, there is a round recess on the mount and a matching ring on the accessory and engages the mount to make the connection very solid. Lot of attention to detail with creative solutions everywhere.

Not cheap, but in all honesty it is worth it.
