What Makes This Stand Out? - The Trijicon SRO shares the same mounting footprint as the RMR, and the enlarged window frame helps shooters to reacquire and track the reticle way better than an RMR.

In addition, couple new innovative features make the SRO extremely user friendly. The SRO is by far the strongest large window sight among other competitors.

However, even though it's strong, but it's not as strong as the RMR for serious duty use to handle physical abuse.

Common FAQ

Why Use A Large MOA Size Dot ?

Long story short, a large MOA size dot is much easier to pick up and above all, it's a much crisp reticle for shooters with poor vision and have astigmatism. (With corrected vision, the reticle will be even more crisp)

The typical smeared reticle or starburst effect is much less noticeable because the dot is bigger. Meanwhile if using a 1 MOA or 2 MOA dot, the starburst overlaps the whole dot, which all the shooter sees is the starburst.

The most popular large dot sizes are 3 and 6 MOA. 3 MOA is the middle ground.

See example below:
