Each passing year brings better red-dot sighting systems with rugged construction, extended battery life and improved designs that are increasingly relegating iron sights to a permanent backup role.

Various designs have brought different strengths and weaknesses to the table, each meeting the various mission requirements. New to the market is the Trijicon Miniature Rifle Optic, or MRO.

The short optical length and large objective of the MRO eliminates the tube effect of most tubular red-dots. And with a battery life of five years of continuous use, the MRO is always there when you need it. Parallax-free with infinite eye relief, the sight is clear no matter your position. Half-minute adjustments up to 70 MOA allow for zeroing in almost any configuration on numerous weapons with no special tools.

Eight brightness settings include two for use with night-vision equipment and one extremely bright setting for bright daylight. In between each brightness setting is an “off” position eliminating the need to cycle to the end.

Placing the adjustment knob on top keeps things ambidextrous.

With a 2MOA dot you get fast target acquisition up close without washing out or losing the target at longer ranges. Tested to operate in temperatures ranging from -60F to 160F, the MRO covers the world. Waterproof to 100 feet, chemical and corrosion resistant and housed in a 7075-T6 aluminum body, the MRO is built to withstand the harshest combat or duty conditions.

Trijicon has once again taken the science of the red-dot sight to the next level. Built to withstand the rigors of combat or mean streets of law enforcement, the MRO sets the standard. Light and rugged, easy to use, mount and zero, with extended battery life and a clear field of view, the MRO does everything you can ask of a red-dot sight.
