SIG Sauer Romeo3 Pro
$699.00
The SIG Sauer® Romeo3 Pro can be directly mounted to the slide using the SIG Pro (DeltaPoint™ Pro) mount. This offers a lower deck height to co-witness with suppressor height sights. Additional brightness settings, easier windage and elevation adjustments, a slightly larger lens and a new magnetic rubber cover have been introduced.
Available with a 3 MOA or 8 MOA dot. Read the full description below for mounting information.
This optic was previously named the Romeo3 Max Pro, but has been renamed and keeps the same SKU and UPC code.
Description
The Romeo3 Pro embodies a lifetime of repetition and experience in the competitive environment.
This optic is fantastic for competition or range use, but we do not suggest it for duty or carry.
Grayguns Slides
This optic is a perfect match for our Lockwood, Mason Lane or Modern Classic P320 custom competition slides.
Romeo3 Pro Red Dot New Features
The next generation of this competition sight builds on the original fantastic features and adds even more.
- Industry-standard SIG Pro (DeltaPoint® Pro) footprint*.
- Flush to slide, direct mounting. No adaptor plate is needed!
- New 8 MOA dot option.
- Easier windage and elevation adjustment.
- A slightly larger field of view.
- A new magnetized rubber cover automatically shuts down the dot.
* A big difference between the Romeo3 and Romeo3 Pro is that the original design used a unique footprint. This updated version uses the PRO (DeltaPoint Pro) footprint. This allows the optic to be installed on a wider variety of slides on the market.
The Romeo3 Pro mounts directly to your favorite compatible optics-ready pistol. The direct mount offers an ultra-low deck height to optimize height over the bore axis.
Available in either a 3 or 8-MOA red dot with 15 total illumination intervals, the Romeo3 Pro allows you to fine-tune brightness settings for any environment.
Romeo3 Pro Red Dot General Features
- Industry-leading 31mm glass aspheric lens with red notch reflector coating for excellent light transmittance, reticle brightness, and zero distortion.
- Crisp red dot reticle, available in various sizes, with 15 brightness settings for rapid target engagement under a full range of lighting conditions.
- MOTACâ„¢ (Motion Activated Illumination System) powers up when it senses motion and powers down when it does not.
- MAGNETAC (Magnetic Activation) turns the optic off when using the included Rubber Sight Cover to preserve battery life between match stages or when storing/transporting the optic.
- Low-profile aircraft-grade CNC Aluminum housing ensures a lifetime of reliable service and allows a co-witness with suppressor-height backup iron sights.
- Dependable waterproof (IPX-7 rated for complete water immersion up to 1 meter) and fogproof performance.
- 20,000-hour runtime from a common CR1632 battery (at medium brightness settings) in a side-mounted tray. There is no need to remove the optic to change the battery.
