I thought I saw something like this on the internet, but can no longer find it. It was a small mount - about the size of a reflex sight base - maybe 3" long and 1" wide by 3/4" thick. It had weaver/picatinny female mounts on the bottom, and male on the top. It also had a red laser built-in. Looked to be designed for a holo sight to clamp on the top of the base, and this base would clamp to my rifle. I need something to raise my holo sight up a bit. Does anyone know if this thing exists? It it doesn't, how can I raise my holo sight up?
