Trijicon outfitted the SRO Adjustable LED Reflex Sight
with a simple but effective 5 MOA red dot reticle that is ideal for
close-quarter work and short-range 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.
