Great optic for the price - Vortex VMX-3T Magnifier with Flip Mount

I use this magnifier on an AR-15 with a Vortex Strikefire RDS. I don't need the high end stuff for recreational shooting and hunting and this system is great for way less than half the price. Eye relief on the mag take a little getting used to. Flip-up feature is a little stiff out of the box, but may get better with use. Overall, a very good value.
