The Trijicon RMR is available in three models with different reticle patterns.  The first RMR model is the LED version.  This comes in a 3.25 MOA Red Dot (RM01) and an 8.0 MOA Red Dot (RM02).  The second RMR model is the Dual-Illuminated version.  There are currently four reticles available for this model: a 13.0 MOA Amber Dot (RM03), a 7.0 MOA Amber Dot (RM04), a 9.0 MOA Amber Dot (RM05), and a 12.9 MOA Amber Triangle (RM08).  The last model available is the Adjustable LED version.  This comes in a 3.25 MOA Red Dot (RM06) and a 6.5 MOA Red Dot (RM07). 

We suggest that you used compressed air to remove any large debris to avoid scratching the lens. Once clear of debris, use an ordinary glass cleaner or car wax. A mild plastic polish will remove minor swirl type scratching. It is important to avoid the use of any strong solvents like lacquer thinner or bore cleaner near the lens as they will damage the lens coatings. Use of a motorized polishing device on the lens will also cause damage to the unit’s lens.

All RMR's are rated to pressures equivalent to depths of 66 feet/20 meters.

The coating is to maximize the efficiency of reflecting the LED's wavelength resulting in a longer battery life.

The RM03, RM04, RM05 and RM08 are battery-free.  The illumination sources for the reticles inside the Dual-Illuminated RMR are tritium and fiber optics.

The RM06 and RM07 battery should last four years of continual use at brightness setting #4. When left on at the brightest setting (brightness setting #8), the battery should last around 25 days.

The RM01 and RM02 models are rated at two years typical use.
