Trijicon outfitted the SRO Adjustable LED Reflex Sight with a simple but effective 1 MOA red dot reticle that is ideal for long-range and bullseye shooting. It runs on one CR2032 button-cell battery with eight brightness settings, including two that are night vision device compatible, with your choice of manual or automatic control. Similar to their venerable RMR, the SRO utilizes the same footprint so it is compatible with most RMR base mounts as well as being directly compatible with most dot sight-ready pistols like the Beretta APX & CX P10. Designed to withstand the rigors of being mounted on the pistol's slide action, the housing is made of 7075 T-6 aluminum with an anodized finish, and at just 1.6 ounces it won't add excessive weight to your pistol.
