Solid mount, precision fit. allowed reflex use with acog base on flattop - Trijicon M16/AR15 Top of Handle Mount RX25 for Reflex Sight

I required an adapter to fit between a GDI quick detach (QD) base and a reflex sight. I had purchased the QD mount as it stated it fit both ACOGs and the Reflex. Turns out they meant the new SRS Reflex sight, so that mount didn't work directly with my older model Reflex sight. This Top of Handle Mount (RX25) was the perfect adapter for fitting between my Reflex sight and the QD base. Fit between this mount and the sight and this mount and the QD base were tight and solid - I have confidence that my sight will maintain a solid zero with it.

The stacking of this mount between the QD base and the Reflex did raise the sight height to slightly higher than the factory thumbscrew base, but I still achieve a comfortable cheekweld without having to add a cheek riser. I cannot cowitness my BUIS, though. But that's not an issue as with the QD base I can just remove the sight if I choose to use the BUIS.
