How I Tested / Evaluation Criteria
Parallax:
I tested each optic at varying distances from 7 to 50 yards. The best performers (RMR and ACRO) showed minimal shift, while budget optics displayed slight deviation when the dot was off-center.
Co-witness / deck height:
Revolver setups complicate co-witnessing. I evaluated how low each optic sits and whether suppressor-height irons could align. Most optics required compromise here.
Durability:
I ran .357 Magnum loads through the MR73 to simulate harsh recoil. Only optics with proven recoil ratings maintained zero consistently.
Battery:
Battery life and accessibility matter. Side-loading and top-loading designs scored higher for convenience.
Brightness range:
I tested in bright sunlight and low-light conditions. Optics with wider adjustment ranges and NV settings performed best.
Glass quality:
Clarity, tint, and distortion were evaluated side-by-side. Premium optics had less distortion and better coatings.
Controls ergonomics:
Button feel with gloves, responsiveness, and placement were tested. Some optics had mushy buttons, which slowed adjustments.
Mounting ecosystem:
Compatibility with MR73 mounts is critical. RMR footprint optics offer the most flexibility.
How to Choose the Right Red Dot for This Gun
Choosing the right optic for a revolver like the MR73 requires a different mindset than selecting one for a semi-auto pistol. The mounting system is often custom, and the recoil impulse is sharper and more abrupt.
First, prioritize durability. The MR73 is capable of firing extremely hot .357 loads, and that recoil transfers directly into the optic. A weak housing or poorly secured emitter will fail over time. That’s why forged housings and enclosed emitters are worth considering.
Second, think about footprint compatibility. Most revolver mounts are designed around RMR or Docter footprints. If you pick an optic with a proprietary footprint, you may struggle to find a compatible mount.
Third, consider window size. Revolvers typically have a higher bore axis, which can make finding the dot slower. Larger windows like the DeltaPoint Pro help mitigate this.
Battery design also matters more than you think. Removing an optic to replace a battery means re-zeroing, which is frustrating on a revolver setup.
Finally, evaluate emitter type. Open emitters are lighter and more common, but enclosed emitters eliminate issues with debris blocking the dot.
