First off, I am a complete optics noob, so forgive me if I am way off base here. I have a Vortex SPARC II on a 9mm SBR. Absolutely hate the thing. Part of my problem is lack of any magnification and old eyes trying to get back on target. Will this RMR be a better option or is it the same style/concept as the Vortex? More of a lateral move?
