Vortex Optics Sport 30mm 싱글 캔틸레버 링 Lower 1/3 코위트니스 - 40mm

This ring locked up on my 30mm tube without any shift after a bit of torque. The offset is long enough to clear my turret housing easily. Feels solid enough to handle the recoil of a .223.

I was worried about cantilever rings feeling flimsy, but this one locks onto my rail and holds zero perfectly even after a few rough range trips. The lower 1/3 co-witness is spot-on for my setup with a 30mm tube scope.

The 40mm offset gave me just enough forward clearance to mount a magnifier behind my scope without crowding my eye relief. The lower 1/3 co-witness lines up perfectly with my BUIS, and the single cantilever design keeps everything rigid.
