## Description

SIG SAUER ROMEO5 1X20 MM TREAD RED DOT SIGHT: The Sig Sauer Romeo5 compact sight provides a robust 1x aiming solution for any situation. Ultra-low parallax so point-of-aim is point-of-impact and the red dot remains parallel to the bore of your gun, no matter what your viewing angle is relative to the optical axis of the sight. Unlimited eye relief allows you to acquire the aiming point and the target regardless of the position of your eye behind the sight. The readily available CR2032 battery is side-loading, allowing for quick battery replacement (featuring 40,000+ hours or more of life). MAIN FEATURES: - 2 MOA Red-Dot provides 10 illumination settings (8 daylight, 2 NV); - Motion Activated Illumination provides optimum operational safety; - Dependable waterproof and fog-proof performance; - Includes M1913 Picatinny low mount riser & co-witness 1.41"" riser mount; ABOUT SIG SAUER: SIG SAUER is an ISO 9001-certified company with over 2,000 employees.

Review: Great optic. - Added this to my PCC build. The brightness adjustment is simple and fast. Covers you from full sun mid day to dim lanes at the range you will find want you want with a few clicks. Has held its sighting with no issues mounted, stored in its case that gets tossed in the back of my truck and then driven through the desert and mountain trails like it’s a rental car. Pull it out and it drives nails every time. Very fast and clean picture which makes follow ups feel smooth. Top thing I like about it is the mount, how high it sits and the ability to co-sight off my irons. I’m not using it to really reach out and touch anything far away with a PCC but it is perfect for my setup. Highly recommend.
Review: Extremely impressed especially at this price - This is probably the best "budget" red dot option. Not sure I would trust it for any actual self defense purposes, but for other purposes I don't think there is a better option out there. I have it mounted to a PCP set up, but I think it would also make a great turkey sight if you are looking for a red dot option. The 2 MOA dot is very clear and easy to pick up. Very well made (not surprising from Sig) and seems like it will hold up very well in the field.

## Questions & Answers

**Q: What is the difference between the Sig sor52001 and sor52010?**
A: That is a darn good question.  I poked around Sig's site and my answer would be "almost nothing" - except for the "tread" printing on the riser mount. Everything else seems to be identical. I do own both and the first 52010 I bought from Amazon a couple weeks ago was DOA as the dot was not connected to the adjuster screws. I got another one and no issue. I think you're safe either way.

**Q: Will this see infrared light ?**
A: According to the Sig Manual it states that it has 8 daytime and 2 NV (night vision) settings. So in theory it should. I, however have not tried it, since I do not own any infrared equip. lights etc.

**Q: What is pictured next to Romeo 5 in the second slide ? Does it come with 2 scopes ?**
A: The right side

**Q: What's the difference between the sig sauer red dot romeo 5 and the romeo 5 tread?**
A: The difference is just the TREAD Branding. This is an accessory branded optics for The Sig Sauer M400 TREAD aluminum frame rifle. Refer to https://www.sigsauer.com/store/sigm400-tread.html for more information.

### ⭐⭐⭐⭐⭐ Great RDS
*by P***Z on December 2, 2025*

This red dot sight is the best investment I have made. Easy Installation, very light weight, and perfectly zeroed. I already attached it to my duty AR 15 DDM4. That combo is unique. Highly recommend. Very happy with the decision made.
