What sets it apart
The reticle gives you two ways to aim. The large circle draws your eye to the target quickly, and the 2 MOA dot is there when you want a finer point of aim. The 509T also carries the MRS designation, and its housing is titanium.
The LED emitter is enclosed. Solar Failsafe is built in, and the optic runs on a CR1632 battery. The lens is multi-coated, and the sight is parallax free, so the reticle stays on point as your eye moves behind the glass.
This optic fits shooters who want a green reticle, a rugged housing and a tan finish that matches Flat Dark Earth gear. It works well for range sessions, practice and general-purpose setups where speed matters more than magnification.
Pair it with a mount that matches your firearm, backup iron sights, a weapon light and a holster or sling in a similar color. Check mount compatibility before you order, since the right plate or base depends on your gun.
