    • Extremely Reliable and Crystal Clear Optic
Style: GEN I Red Dot Sight - Black (SOR52001)
The SIG SAUER Romeo5 1X20mm Red Dot Sight has exceeded my expectations. The red dot is crisp, clear, and easy to pick up quickly, which makes target acquisition fast and effortless. The brightness settings are easy to adjust and work well in both bright daylight and low-light conditions. The build quality feels extremely durable. It’s solid, waterproof, and fogproof, so it holds up well in different environments without any issues. The included Picatinny mount made installation simple, and once mounted, it stays secure with no movement. Battery life has been excellent, and the motion-activated feature is a great bonus. It turns on when needed and helps conserve power. Overall, this is a dependable, high-quality optic that performs exactly as advertised. Definitely worth it. ... show more

    • Incorrect information in some reveiws!
Style: GEN I Red Dot Sight - Black (SOR52001)
I received this in the factory sealed box, and with the factory tamper proof seal in tact! The sight came boxed with the, Mounting key, Lens cloth, Battery, 2 mounts, lens cap, Instruction Sheet. This is a very nice sight, easy to mount, clear optics. Clearing up the misinformation about this sight. A few things that's important to know about the optic! (1) Read over the instruction sheet, don't just think you've had these types of sights before and you know how this one works and end up leaving bad reviews. (2) Yes! the sight has an auto off after 120 seconds of "No Motion" and auto motion ON so, yes if it stored in a vehicle the motion of it will keep the red dot illuminated and cause an unnecessary battery drain. If you've read the instruction sheet it informs you that the sight also an actual Power Off and Power On option, to use this option you only have to hold down on either the + or - button longer than 1 second, and the same thing to power it back on. (3) reports of the sight not working in MOST cases is caused from one of couple of things, when you first install the battery you will not be able to see the red dot until you turn up the brightness, so click the + button (Don't Hold It Down At First, Just Click It) 3 or 4 times if you still don't see the dot assume the sight is in its Powered Off Mode and push and hold either the + or the - button for 1-Second to actually turn the sight on, then click the + (plus) button a few times until the dot becomes bright enough to see. (4) Another possible problem that could happen is with installing the battery, mine had a safety peel off sticker that HAS to be removed, well due to certain conditions when you peel these off it leaves adhesive (glue) on the battery so its possible to leave enough as to cause a loss of battery contact. Make sure when you peel the sticker off from the battery that all the adhesive is cleaned off of the battery itself. _______________________________________________________________________ !Caution! the brightness adjustments in either direction ISN'T A PUSH & HOLD operation!!!!! its momentary CLICKS! That means that the brightness setting isn't a constant veritable, its in CLICKED STEPS! !Caution! holding down for more than one second on either the Plus or the Minus button actually turns the optic sight OFF (totally powering it down) meaning that just clicking the brightness buttons (Plus or Minus) will not do anything until the optic sight is "Turned Back On" Bottom line on the misinformation of this optic, its has some higher level electronics then the standard red dots, its not rocket science to understand, but its cause for a lot of these being returned and the reason for a lot of the low rated reviews. Its NOT only "Auto Powered Controlled" it can be Turned Off, and it can be done so by accident. PLEASE read over the instruction sheet FIRST before you box this sight up and return it, its quality enough to deserve that much attention. Bottom line on the optic sight itself. Let me make this clear! This review is from a 64 year old AR-15 (5.56 NATO) gun owner!! The sight responded well to adjustments! Seems to be holding ZERO very well with what ammo I've fired so far! It has very clear optics! Having the turret adjusting bits built onto the turret caps works very well! There is no issues with the quality or function of this sight that I can find, but I'm thinking that the same sight upgraded to the larger tube and lenses might be NICE! but it would be larger and it cost more! Very Nice for the money! ... show more

Style: GEN I Red Dot Sight - Black (SOR52001)
Dot brightness very good. Easy to mount. (2) available pic rail mounts are included for height preference. Easy to zero. Comes with battery, mounting/adjustment tool, lens cloth and bikini-style lens cover. This version looks better than the newer models (in my opinion). Generally a great red dot. I'll get another one soon. ... show more

    • Battery cap not knurled on Gen1. Not a deal breaker, but needs to be noted.
Style: GEN I Red Dot Sight - Black (SOR52001)
Sight was as expected. I own a few of them. Just note that the battery cover on the most recent one I ordered is no longer knurled. I did purchase the Gen1. It is not a big deal since it has shake awake and auto sleep, but it might be important to some people. The battery cap in the Amazon ad is not correct. ... show more

    • Stupid simple great
Style: GEN I Red Dot Sight - Black (SOR52001)
So I actually bought this a few years ago. I put it on my duty AR. I really didn’t use it except once a year to qualify at the range. I keep the cover on to keep the glass from getting scratched. Recently I bought a new gun and it came with no sights. I took the riser off of this and placed it on that gun to try it out. The battery even after being in my car all this time is fine. After adjusting for windage and elevation it worked great on my new 10/22 charger. Playing with the adjustments was not too difficult after getting the caps off. Put the dot where you want the bullet to go and it was dead on even if I looked at it through weird angles. I normally use iron sights but this convinced me to re-think that. I am considering putting this in my 22/45 next. Sight acquisition is faster the more you use it. Long battery life. Ease of use and it has both the riser and low mount so can work with pistol or rifle. The price is right and even on low settings works outside in the sun. Better than night sights in the house for home defense and you can shoot with both eyes open. It’s durable. I had this mounted and banged around in my patrol car a lot. It still looks like new. And it functions flawlessly. I will say this. It is designed by Sig Sauer but says right on the body of it made in china. Still what works, works. ... show more
