The Trijicon RMR probably has the best reputation among pistol optics for defense and duty use. It’s made from 7075-T6 aluminum and has a patented shape that absorbs impacts and diverts stress away from the lens, increasing durability. We offer the most popular and effective adjustable LED models. The New RMR Type 2 has redesigned and upgraded electronics which have proven through extensive testing to properly function when mounted on pistol slides and other small arms. Also included in the new RMR Type 2 are button lock-out mode and battery-saving features, which make this optic ideal for concealed carry and law enforcement use. With eight available brightness settings, the reticle can be manually adjusted by pressing the plus or minus buttons on either side of the unit. To switch to auto adjust mode simply press both buttons simultaneously and release. To save battery life turn the optic off by pressing both buttons simultaneously and holding for 3 seconds.
