Features of Sig Sauer Romeo4A 1x20mm Red Dot Sight Low .5MOA SOR41001:

  • Stealth ID deflection armor trapezoidal surfacing breaks up the shape and visibility of the optic along with pistol slide serrations and grip checkering to add function to the form.
  • Highly efficient, ultra-wide broadband, anti-reflection Spectracoat lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission.
  • Unlimited eye-relief allows you to acquire the aiming point and the target regardless of the position of your eye behind the sight
  • Dual reticle option, on select models, toggle between 2 MOA red dot or circle dot (2 MOA red dot with 65 MOA circle)
  • Utilizes an ultra-efficient red LED illumination system for daylight visibility with extended runtime and mil-spec objective coatings to limit downrange light leakage in tactical situations.
  • Features MOTAC (Motion Activated Illumination System) that powers up when it senses motion and powers down when it does not. Provides for optimum operational safety and enhanced battery life
  • 50,000+ hour battery life and the readily available CR2032 battery is side-loading, allowing for quick battery replacement.

This is a great Red Dot optic for my Sig Sauer MCX 5.56 Carbine. The glass is clear and crisp. The Red Dot feels very durable and dials are easy to manage. Sig Sauer did a really great job with this Red Dot.

purchased this red dot over a month. I put it on my BCM SBR and it works great. Zeroed it for 50 yards and ran about 400 rounds through it. Awesome red dot so far. I would recommend to friends and family.

I bought this red dot at 50 percent off last year and sold it with my Ar15 to a buddy of mine. Long story short we were hitting .5 inch groups at 300 yards with this. Yes you heard that correctly. I would say the max range for this red dot is 350 yards depending on the size of your target. We were hitting a12x12 steel target.

It's a fantastic red dot, especially if you need to get a really low profile, like on a RS Regulate mount. It has some limitations, and if you have the money, get a newer model like the 4h, but it's still an incredible deal at it's price point

This is my 2nd Sig Sauer red dot sight. I was impressed with the price/quality of my Romeo 5 and decided to try another. The rail on my M1A CQB is forwardly placed And the eye relief on this sight matches it well. Accurate enough out of the box. With the low mount it has a sleek modern look. With the supplied tall mount, not so much.
