Ade Advanced OpticsAbsolute Co-Witness Riser HIGH Mount - Compatible with Meopta, Insight, Eotech MRDS, Sightmark Mini Shot Red Dot Sights

Quick service. Good fit. Easy mounting with all hardware supplied. Finish is good. Would use again

I bought model HM2 from Optics Factory because they didn't offere it on Amazon, but I was very impressed on the exact fit. I used it for an absolute co-wittness on my AR-556 using the Riton X3 Tactix and all I can say is UNBELIEVABLE!

Great mount! I'm very happy with it.
