Perfect addition to a red dot - Riton RT-R Mod 3 3X Magnifier

Not much can typically be written about magnifiers - they do one thing. That said, this particular unit is very well thought out and rugged to boot. This was my first Riton purchase (along with their red dot) and not only is it perfectly aligned (you wouldn't believe how often this isn't the case) but it's very easy to manipulate and looks great. It also flips to the strong side for right handed shooters; lefties can just flip the optic in the mount (again, you wouldn't believe how often this isn't properly solved for).

This unit, along with their red dot, made me a fan of Riton, and I've made more purchases since then. Highly recommended.
