Good solid qc mount - Sightmark 30mm/1in QD Mount

It’s one ring for single point attachment. Don’t expect a pair. I use it the mount a cheap magnifier that came with a really bad flip to side mount. It’s well made, and I’d definitely buy another. It lined up well with my Vortex Strikefire II optic which is a pretty high mount red dot. You would want the short one, if you intend to use it the way I did with a low optic.
