Style: Green Dot Sight - Black (SOR5102)
Build quality is so good for the price. Engineered and manufactured well. These type of sights have gotten really good lately. Includes 2 different height mounts that are awesome quality as well. $150 for the green dot and done. Good job Sig.

Style: Red Dot Sight - Black (SOR5101)
I picked up the SIG ROMEO5 Gen 2 after using the original model for years—and I’m seriously impressed. SIG took a great optic and made it even better. The 2 MOA red dot is super crisp and easy to acquire, whether you’re at the range or out in bright sunlight. It has 10 brightness settings, including two for night vision, and the motion-activated MOTAC system is a game changer. The dot turns on instantly when you pick up your firearm and turns off when it’s idle—saving battery without any hassle. I’ve been running the same battery for months with no issues. Mounting was quick and easy, and I love that it comes with both a low mount and a co-witness riser. I’ve got mine on an AR-15, and it hasn’t lost zero after hundreds of rounds. Super rugged, water-resistant, and compact—perfect for a range of platforms. Bottom line: If you want a reliable red dot that punches well above its price point, the ROMEO5 Gen 2 is it. Ideal for beginners and seasoned shooters alike.

Wow. Going from generic Amazon optics to this one is night and day. Easy to zero, clear view, and my astigmatism doesn’t seem to have any effect on this optic, even when mounted forward of the bolt. Glad I dropped the extra coin for the confidence of the MOTAC, and a clear and easy target acquisition

This is a great little sight. It’s rugged for what it is, the dot is very bright, the glass is clear and it’s easy to adjust. Now the downside, the battery was dead on arrival which is fine but the cap was almost impossible to remove. It also didn’t work with my astigmatism and was a smear instead of a dot, which is strange because the one that I tried in the Sig Flagship store was perfect. This one sadly is getting retuned.

I have a 4T and wanted to see the difference between cheaper models. Pros: build quality feels just as good. The Romeo 5 feels good and robust in the hand. Having the Motac feature is also nice at this price point. Also, nice mounting options included. Looks a lot like a reptilia mount and it’s free. Cons: honestly just the glass quality and reticle clarity. With the 4T the dot is crispy and nice. The Romeo 5 is a legitimate starburst of squiggles with no defined center point at usable brightness. There’s also more hue in the glass. The 4T is very clear regardless of which reticle you use. It’s a good buy, but know what you’re giving up.
