The Trijicon RMR is
designed to improve accuracy and precision with any firearm it is attached to.
The sight is very durable because its housed in forged aluminum. The Trijicon
RMR is exceedingly durable and very lightweight. It's also extremely simple to
sight in with the audible clicks. It will perform under the harshest operating
conditions thanks to the high-strength of the housing, forged,
military-grade, aluminum that absorbs shock. The reticle is red and
takes a CR2032 battery (battery life 1700hrs and the battery is
included.) Also with the RMR you can turn it off by pressing both buttons
and holding for 3 seconds. Once the Trijicon RMR is on one firearm you
will want it on all your firearms!
