Trijicon RMR Type 2

Trijicon RMR Type 2

The RMR Type 2 is overbuilt for a .22LR pistol—but that’s not necessarily a bad thing.

Specs

  • 3.25 MOA dot (common variant)
  • RMR footprint
  • Bottom battery (CR2032)
  • Forged aluminum housing

Pros

  • Extremely rugged
  • Proven durability
  • Clear, distortion-free glass

Cons

  • Requires removal for battery change
  • Higher deck height

My hands-on notes
Parallax is negligible in practical shooting. The higher deck height makes co-witness more difficult on a TX22 without taller irons. The dot is crisp, but the emitter can be partially occluded by lint or debris if not maintained.

What people say online
Widely considered the gold standard. Many shooters admit it’s overkill for rimfire but appreciate the reliability.

Mounting clarity
Requires an RMR plate—TX22 users must ensure compatibility.

Vortex Venom

Vortex Venom

The Venom is a classic budget-friendly optic that still holds up surprisingly well on rimfire pistols.

Specs

  • 3 MOA or 6 MOA options
  • Top-load battery
  • Docter/Noblex footprint
  • Aluminum housing

Pros

  • Easy battery access
  • Large window
  • Affordable

Cons

  • Slight lens distortion at edges
  • Buttons can feel mushy

My hands-on notes
Parallax is noticeable at extreme angles but acceptable for casual shooting. The large window helps compensate for slower dot acquisition. Co-witness is achievable with the right plate setup, though not as natural as RMSc optics.

What people say online
Popular among budget-conscious shooters. Many note it performs above its price point on .22LR platforms.

Mounting clarity
Requires adapter plate—does not directly fit RMSc footprint.

How I Tested / Evaluation Criteria

Parallax
I tested each optic by shifting head position at 10–25 yards. The best performers showed minimal point-of-impact shift, which is critical for a training pistol like the TX22.

Co-witness / deck height
Lower deck height optics felt more natural and allowed better alignment with iron sights. Taller optics required adaptation and slowed first-shot acquisition.

Durability
Even though .22LR recoil is light, repeated cycling exposes weak electronics and mounting systems. I looked for zero retention and consistent illumination.

Battery
Side-loading batteries are significantly more practical. Bottom-loading designs like the RMR introduce re-zeroing inconvenience.

Brightness range
A good optic must handle both indoor range lighting and bright outdoor conditions without washing out.

Glass quality
Lens clarity, tint, and edge distortion all impact usability. I paid attention to how clean the dot appeared under different lighting.

Controls ergonomics
Button size, tactile feedback, and usability with gloves were all evaluated.

Mounting ecosystem
Compatibility with RMSc or adapter plates is critical for the TX22 platform.

How to Choose the Right Red Dot for This Gun

Choosing the right optic for a Taurus TX22 is different from selecting one for a duty pistol. The TX22 is primarily a training, plinking, and competition-adjacent firearm, which means priorities shift toward usability, weight, and cost efficiency rather than extreme durability.

First, footprint compatibility matters more than most people realize. The TX22 often uses RMSc-style mounting, which makes optics like the Holosun K-series and RomeoZero much easier to install. Using an adapter plate introduces extra height, which affects your natural point of aim and co-witness capability.

Second, consider weight. Rimfire pistols are more sensitive to slide mass. Heavier optics can affect cycling reliability, especially with lower-powered ammunition. Lightweight optics like the RomeoZero or 407K tend to maintain smoother operation.

Third, think about your use case. If you’re using the TX22 for steel challenge or rapid-fire drills, a larger window or multi-reticle system can improve speed. If it’s strictly for training fundamentals, a simple 3–6 MOA dot is more than sufficient.

Battery design is another overlooked factor. Frequent shooters will appreciate side-loading batteries, as they eliminate the need to remove the optic and re-zero.

Finally, durability still matters—but not at the expense of usability. Overbuilt optics like the RMR are excellent, but may not provide practical benefits on a .22LR platform compared to mid-range options.

FAQs
