Expert Review

Great all around red dot

by Matt S., Gear Expert from IL, United States Written on September 3, 2019
Really great red dot that offers a lot of features without breaking the bank.

Black and tan rifles always look good to me so I went with this primarily for the FDE finish.

I really like the circle dot reticle, crisp and useful without feeling like it's cluttering the window.

AAA power source is super easy to find and offers solid battery life. Easy to access battery compartment is very convenient.

While I don't love bikini covers usually, the included ones are very nice for storing/transport purposes.

The Motion Activated feature makes this a great choice for home defense setups.

I paired this optic with the Romeo4 magnifier on a 12.5 inch AR and it really makes for an affordable but capable setup (basically HHS for half the price)
Most Helpful Positive Review Just a nice clean red dot that performs and runs
The color is fantastic. it appears to be a enamel sprayed finish. I love that it is always ready to go while not wasting battery life thanks to the motion activation technology built into this sight. The dot is crisp and when shooting with both eyes open the sight outline really disappears making it...

Most Helpful Negative Review Defective out of the box
I had high hopes for this optic based on all the positive reviews that I have seen/read. Opening the box you notice that they took time to showcase this optic very well. Everything is organized and laid out. Examining the OPMOD Romeo5 before installing on my rifle and everything looked good, I didn’...

Great replacement for Bushnell TRS25

by Hedge, Verified Owner from OK, United States Written on October 14, 2023
I wanted something ready to go when I pick up the rifle. As usual the fit and finish of Sig products is great. Packaging is Sig flawless. Scope caps fit perfectly. Shake awake is awesome. So much better than just turning the dot on. Triple A battery is easier to find in a pinch. Battery life is out of this world although I haven't killed one battery yet. I found the reticle to be very clear and sharp. This model has the upgraded emitter that is different from the Romeo 5. Turrets were crisp and the adjustments were fine. Call me a snob for wanting 1/4 adjustments in everything but this worked great. The selectable reticle is nice and the "Eotech" reticle fits perfectly to co witness with my Midwest industries rear and Magpul pro front sight with stock riser that was attached although it comes with another riser. It was almost perfectly zeroed at 50 yards out of the box which was nice. Lockup was tight and it has held zero on both the 5.56 and 7.62x39 uppers. I will again trust the durability videos on the internet as I don't drive over my scopes with my truck. This is a durable piece it seems. Feels like quality.

I would say for a red dot at this price it blows most everything else away. It's giving you everything you need except that really big objective but that's the only thing it misses. If you are worried about seeing the front emitter I can tell you it can be visible at close range but unless you go another more expensive route that is the case with all red dots. And i...

Very Solid Option

by Jim, Verified Owner from CT, United States Written on September 14, 2023
Extremely clear glass for the price point. It has a great reticle and has the single dot option too. It also looks excellent under magnification. The only downside is that it has limited mounting options. However, if you like Full Co-Witness dots and the donut of death, this is a great entry level option. And it comes in FDE! Nice product.
Pros:
  • clear glass
  • Affordable
  • good reticle
  • fde
  • Looks Good Magnified
  • Fast Sight Aquisition
Cons:
  • Limited mounting options
Best Used for:
  • Home Defense
  • day shooting
  • Civilians
  • Night Shooting with White Light
  • Full Co-Witness with Iron Sights

Issues out of the box

by Potomoto150, Verified Owner from PA, United States Written on August 20, 2023
You get what you pay for. Its cheap for a reason. Ive had nothing but issues from the time I opened the box. Intermittent power. And finally a year later it no longer works at all. Assuming theres no warranty so just wasted money. If youre looking, spend your money on something better.
