Just zeroed in my Vortex Micro3X Magnifier with my Aimpoint Pro. It's a great magnifier for the best price. Thank you Guidefitter! You guys saved me cash! The only bad thing is that I don't have backup iron sights because the picatinny rail cannot accommodate the red-dot magnifier and irons, due to the rec7 piston system. Other than that very happy with it. The magnifier helps my old eyes out, and the warranty with Vortex is spectacular.
