FOV Comparison 

Lens Frame

trijicon rmr vs sro FOV comparison

This one is obvious! The Trijicon SRO has the largest circular shaped field of view to help find the dot faster.

This is great for offset red dot, shotgun, rifle and pistol applications.

The Trijicon RMR's field of view isn't too bad, but it's much harder to go back to it once you have tasted the Trijicon SRO.

Dot Sizes

Referenced Trijicon

Both optics offer a wide selection of dot sizes from 1 MOA to 13 MOA. 

Trijicon RMR LED offers: 1 MOA, 3.5 MOA , 6.5 MOA (1 MOA is the best for precision shots)

Trijicon RMR illuminated offers : 7 MOA, 9 MOA, 12.9 MOA and 13 MOA (Great for outdoor use and users with severe astigmatism)

Trijicon SRO offers: 1 MOA, 2.5 MOA, 5 MOA (5 MOA is the best for pistol use)

Lens Tint

Both RMR and SRO have lens tint, but the Trijicon RMR has the darkest blueish tint. The Trijicon SRO's lens is fairly clear.

In low light conditions, the Trijicon SRO is the winner. For Trijicon RMR, a weapon light is definitely required to lit up the target without being obscured by the lens tint.

Mounting Footprint

Both optics feature the same footprint. Any existing RMR optic mounts will work. See more RMR optic mounts here

Battery Compartment

trijicon sro battery access

Trijicon SRO has a way better battery compartment design than the SRO because the user can access the battery without removing the sight from a mount.

Trijicon RMR's bottom battery installation can be annoying if the user needs to switch the battery, but don't have the right tools.

Durability

Lens Frame Durability

Both optics can handle drop and field bruises. However, the original Trijicon RMR has a more rugged lens frame that can divert point impact stress away from the glass.

trijicon sro profile

The SRO's circular shape lens frame is not engineered to do that from the top or sides.

Most handgun users will use the optic as a lever to help charge the slide faster, and both optic are great for that.

For charging the slide on hard surfaces, the Trijicon RMR is better suited.

Emitter Reliability

Both optics are open emitter designs.

  • Under normal use, both optics are reliable. 
  • Conceal carry under clothing without cleaning - Dirt and particles can fall in there and obscure the emitter screen
  • Under rough weather conditions such as sandstorm, mud, rain, snow - They can block the emitter screen
