Riton Optics XRC30QD Contessa QD 鏡座環組合 黑色陽極處理 30mm 0 MOA

I was a little worried about QD mounts holding zero, but these clamp down rock-solid with those six screws per ring. The machining on the steel feels really precise, and the lever snaps into place with a satisfying, secure click.

These mounts lock onto the rail with zero play and the six screws per cap give me real confidence the scope won't shift. Installation was straightforward and the return-to-zero after removing and reinstalling has been spot-on so far.

I swapped out my old rings for these and the difference is night and day—the steel construction feels solid and the quick-detach feature locks up tight with zero play after remounting.
