Any Green/Red dot scope that will fit out there??

[slugster1187]

I have a Ruger Redhawk 44 magnumwith factory scope mounts on the barrel which are 2.5 inches apart from center, with the rings in place I have only 1.75 inches of scope play. My question is,Is there a Red and Green dot scope out there that will fit within the 1.75 inches of the two scope rings?The scope tube can be 1" or 30mm. Thank You

Why not just use an regular optical scope,or a scope with illuminated reticle? I'm sure 1 of those would fit, and make for more precise aiming at the same time.
