Trijicon RMR

Trijicon RMR Type 2.jpg
First, the RMR is an incredible piece of gear, but let's be honest, it's overkill for a .22LR pistol. Here's the breakdown:
Specifications
Magnification: 1x
Reticle: Available in various MOA dot sizes (3.25, 6.5 commonly seen)
Objective Lens: Varies by model
Brightness Settings: Manual or Automatic options depending on the model
Battery: CR2032 (Years of life depending on settings)
Weight: ~1.2 oz (34g) depending on model
Mount: Requires specific adapter plates
Best Features
Tiny and Tough: The RMR is famous for its compact size and extreme durability. It can handle anything, even if the SR22 probably never will.
Sharp Dot: Trijicon delivers a crisp red dot with multiple reticle size options for precision.
"Always On" Reliability: With the right model and settings, your sight will always be ready to go.
Advantages
Super Lightweight: Keeps your SR22 feeling agile and easy to point.
Target Focus: The small RMR keeps your focus on the target, not the optic itself.
Disadvantages
Pricey Overkill: An RMR could cost more than your Ruger SR22! The extreme durability isn't necessary on a .22 LR target pistol.
Mounting: You'll need a specific adapter plate to mount the RMR to the SR22's dovetail, adding another layer of complexity and cost.
Dot Size: Depending on your eyesight and model, the small RMR dot might be tougher to pick up, especially for newer shooters.
My Experience
I've tried friends' pistols with RMRs, and they're amazing optics... on the right guns. For the SR22, I'd prioritize a more budget-friendly, simple red dot. You get 90% of the performance for a fraction of the cost.
Online Comments/Discussions
It's a mixed bag when it comes to RMRs on the SR22:
"Love my RMR, but honestly, it's too much for my .22."
"Tried it, sold it, and got a Holosun - way better value."
"If you have the money and want the best, RMR all the way."
The Takeaway: The Trijicon RMR is a legend, but for the SR22, there are more practical, budget-conscious red dots that will deliver a very similar shooting experience.

Conclusion

The best red dot for Ruger SR22 boils down to your main focus. If precision target shooting is the name of the game, a red dot with a small MOA and crisp dot is ideal. However, for plinking or training purposes, wider field of view and larger MOA dots can enhance the shooting experience.
