Hunters or shooters will appreciate the intuitive operation for fast setup and ease of employment.

The Romeo 5 delivers excellent performance and reliability for an unbelievable price. If you are looking for a reasonably priced versatile red dot sight, then consider the Sig Romeo5.

DESIGN

This Romeo 5 series has a compact tub style form factor made with a matte finished aircraft-grade aluminum chassis weighing only 5.1 oz. It is designed with Sig Sauer's reflection armor trapezoidal surfacing. The surfacing is intended to break up the optic cylindrical shape and visibility of the optic aiding in the shooter’s signature reduction. 

The optic  has an overall length of 2.47 inches with a width of 1.5 inches  and a height of 1.52 inches, weighing only 5.1 oz (with 1.41” riser mount and battery) making it the lightest of the Romeo5 series. 

The sight has an Ingress protection of X7 (IPX-7).  This rating means that the optic can withstand immersion in up to 1 meter of water.  With this rating, you can expect excellent dependability and fog-proof operation under wet and high humidity conditions.  

Lenses

You can expect clear viewing through this 1x magnified sight with lenses that have excellent light transmission. This red dot sight includes glass lenses coated with Spectracoat. This lens coating is highly efficient and enables viewing across an ultra-wide band of the visible light spectrum.

The coating has excellent anti-reflective qualities reducing surface reflections to extremely low levels. The lenses deliver quality viewing under various lighting levels, making target identification and acquisition quick and easy, all with the added benefit of a reduced signature when a stealthy approach is required.

OPERATION

The illumination controls are mounted on the top of the sight. Simply press and hold either the (+) or (-) button longer than 1 second to turn the sight on.

Press and hold either the (+) or (-) button longer than 1 second to turn the LED dot off.

The Romero 5 has a maximum windage and elevation adjustment of +/- 40 MOA. The adjustments are in .5 MOA increments with a flat edge utilizing top and side-mounted adjustment knobs. 

With .5 MOA adjustments, you can achieve a level of precision that will allow for accurate shooting from close to intermediate distances. And with the rugged design, you can expect no change of Point of Impact (POI) no matter how many rounds you put through your rig. 

The sight uses a single CR2032 lithium coin cell battery that will provide up to a 40,000 + battery life depending on what illumination setting is used.

Changing the battery is accomplished from the side. This reflex sight is considered parallax-free, so you can expect the point-of-aim to be the point-of-impact. The sight has unlimited eye relief to acquire your target from any eye position behind the optic. 

Motion Activated

The Romeo 5 is outfitted with Sig Sauer's Motion Activated Illumination (MOTAC) feature that powers up the sight reticle when it senses movement. Conversely, if the optic remains at rest without motion for 2 minutes, the reticle will power off. Motion-activated reticles enjoy the benefit of extended battery life, keeping the Romeo 5 ready for action when it’s needed. 

RETICLE

The Sig Romeo 5 (SOR52001) utilizes a 2 MOA red dot reticle. The reticle has ten illumination settings selected through plus and minus buttons located on the optic’s top. Eight of the brightness setting are for daylight and other bright light operating environments.

The remaining two settings are for night vision or low light operating environments. With ten illumination levels, the sight can function in almost all light conditions, given the shooter or hunter plenty of employment options.

MOUNTING

The sight is ready to mount on a standard Picatinny/MIL-STD-1913 rail. Included is a 1.41-inch riser for a co-witness mounting option. Additionally, you can use it in a low-profile mount more suited for pistol and shotgun setups. The mount is adjusted with the included T10 Torx wrench. Switching between mounting options is easy.
