Primary Arms Classic Series 1x25mm Push Button Red Dot Sight w/3 MOA Dot Black. With its wider field of view the RD-25 offers greater visibility and situational awareness when looking through your optic. The RD-25 has also undergone extensive recoil and field testing to prove that it is just as durable as more expensive optics so you can be confident that this microdot will last. Not only is the aluminum housing extremely durable but it features fully multi-coated lenses that are anti-reflective and fog resistant and has been rated at IP67 for water resistance. The high-power LED emitter provides plenty of visibility even on the brightest days and the top mounted buttons make it easy to cycle through all 10 brightness levels. Right out of the box the RD-25 red dot sight comes with a rugged and lightweight QD mount with an adjustable tension lever so you can don't have to worry about shopping for a new mount. However it still uses the industry standard mounting footprint so you can pair it with the Primary Arms Micro Dot Offset mount for use with either the 3x or 5x MicroPrisms. Precision for any budget. Classic Series optics and accessories are perfect for the budget-focused marksmen. All Classic Series products come with a lifetime warranty showing their commitment to guaranteed quality.
