Red dot magnifiers have been around for over almost two decades. These specialized scopes allow users to add magnification to their red dots. But for prism scopes, magnification has been fixed due to their limited eye relief. Monstrum did something innovative.
The Ghost magnifier is the first of its kind that I’m aware of that fits forward of the aiming optic instead of behind it. This allows the GHOST to work with both red dots and prism scopes; converting a 4x prism scope to an 8x. It comes with a side-flip mount.
