Trijicon claims a four-year battery life under continuous use at brightness setting number four for the Adjustable LED RMR. When left on at the brightest setting (brightness setting number eight), the battery is said to last around 25 days. The RMR is just 1-inch tall, but it has a generous 1Ã1 1/16-inch sight window that aids rapid, both-eyes-open, target acquisition and an unobstructed panoramic view for maximum situational awareness. Its eye relief is effectively unlimited. The RMRâs non-magnifying lens receives a 28-layer coating that Trijicon calls True-Color.
As the name suggests, the Trijicon RMR (Ruggedized Miniature Reflex) is both tough and small. Housed in forged aircraft-grade aluminum, it is also lightweight, and all RMRs are rated waterproof to pressures equivalent to depths of 66 feet. The Trijicon RMR is available in three models with different reticle patterns. The first is the LED version, which is available in a 3.25-m.o.a. red dot and an 8-m.o.a. red dot. The second model is the Dual-Illuminated, which currently is available with one of four reticles: a 13-m.o.a. amber dot, a 7-m.o.a. amber dot, a 9-m.o.a. amber dot, and a 12-m.o.a. amber triangle.
