Trijicon RMR Battery VS Tritium – Which Is Better?

Which one is better, Trijicon RMR fiber optic vs battery operated?

There is a lot of questions regarding which one to get and why one is better than the other.

In this article, we gonna briefly go over what’s different about them, and share our thoughts.

Trijicon RMR Battery VS Tritium Models

RMR is very popular for handguns, rifles and shotguns.

The RMR Type 2 models offer redesigned and upgraded electronics that are proven to perform when mounted on slide ride pistols and other small arms.

How Tritium Works

The tritium fiber optic gathers the surrounding light to illuminate the reticle in low-light conditions, and fiber optics automatically adjust the brightness level and contrast to available light conditions.

During day time, an RMR with tritium insert works very well. The reticle is bright to see on a sunny day or a cloudy day.

However… in low light, the Tritium is basically useless, and using a weapon light for PID at close ranges can washout the dimmed reticle even more to the point you can’t even see.

Reliability – Low Light Performance

Both optics are very reliable as far as external and internal components,

But…The battery powered RMR is the most reliable.

The LED reticle is always visible in any lighting condition without relying on ambient light source. This is great for any home defense and conceal carry guns.

On the another hand, Tritium fiber optic RMR doesn’t work when there is no light source to illuminate the reticle.

Reticle Options

The adjustable LED RMR offers:

  • 1 MOA – Finest dot for precision shooting and shooters with aged eyes
  • 3.25 MOA – Most versatile and popular of all RMR dot sizes
  • 6.5 MOA – Biggest dot available in Adjustable LED-operated models

The Tritium dual illuminated RMR offers:

  • 7 MOA – Standard for tritium RMR
  • 9 MOA – Chosen by USMC for use in both the SDO and MDO optics
  • 12.9 Triangle – Use tip of the triangle for precision shooting
  • 13 MOA – Recommended for any CQB and shotgun applications

Lens Tint

Both RMR models have a slight blueish lens tint on the glass, which isn’t a big deal in outdoor environments with natural sun light and ambient light.

However, during low light environment the lens tint can slightly reduce the clarity of the lens, and the being able to adjust the reticle brightness intensity is a important feature to adjust relative to the lighting condition, which is why the adjustable LED RMR model is the preferred for conceal carry users and any home defense guns.

MOA Adjustments

Both optics have 1 MOA / Click adjustments for elevation and windage. Each click gives you positive and auditory feedback.

The max adjustment range is 157 clicks for both windage and elevation.

Mounting Footprints

Both optics share the same mounting footprints, so no differences here.
