ROMEO5 compact red dot sights provide civilians and armed professionals 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 firearm, 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 50,000+ hours or more of life). Dependable waterproof (IPX-7 rated for complete water immersion up to 1 atmosphere) and fog-proof performance.

  • -Dependable waterproof (IPX-7 rated for complete water immersion up to 1 meter) and fog-proof performance

I ordered the sig romeo 5,,the low mount was not in the box.the box was sealed.??
richard d on Jan 18, 2019
BEST ANSWER: Same here on mine (arrived today). If they don't answer my email, I'm contacting my bank to dispute the charge on my credit card. The description on this very web site for this product CLEARLY states "-Includes a M1913 Picatinny low mount riser and a co-witness 1.41” riser mount", yet it's missing the mount. This is a problem!
Will the romeo5 mount on an ar with the carry handle?
Marv H on Jul 22, 2018
BEST ANSWER: You would need to purchase a rail that uses a single thumb screw that mounts on top of your carry handle. Then you can mount any scope or red dot type sight to the rail on top of your carry handle. Some carry handles can be removed so if yours is the removable type the red dot will mount right in place of the carry handle.

David L on Jul 23, 2018
BEST ANSWER: It is compatible with night vision if you have it, that's what the first two settings are for. You have to have night vision Togo behind the scope.

Can it withstand a 308?
jaymo on Sep 11, 2018
BEST ANSWER: It would probably handle the stress, however, ask yourself this. MOST people buy .308's for 500 yard+ shots. A red dot is probably good for, tops 100 yards, as they're not really designed for long range. Why would you not spend a bit more and get something designed for longer distances?

will this red dot be blocked by a perm mounted A-2 front sight ?
JAMES D. Q on Sep 19, 2018
BEST ANSWER: No, it shouldn’t be a problem. It will cowitness. The mounts are good quality, too. Similar to a Daniel defense aim point mount. The ones I bought are the CR2032 battery model. If you get the AAA model, it will also work.

Look at the manual online. I can’t link to it.

what type of range would you have with a ar15 223?
Leroy S on Feb 9, 2019

Great red dot with lots of brightness settings. I love that I never have to turn it off. And it turns on on it’s own when you pick it up. Nice crisp dot and it looks amazing mounted. Best dot I’ve ever bought and it’s very affordable.

Great Sight
This is a great sight for the money. The only issue I have had is getting the sight to turn on quickly. There appears to be a delay in the switch, other than this it works well.

The best for the money red dot anywhere!
This thing co-witnessed with my AR sights right out of the box!!!! It is by far the easiest and most cost efficient upgrade I've made to two of my rifles. Awesome red dot for the money. I also saw a torture test video on YouTube showing how bomb proof this thing is. Do yourselves a favor and pick up as many as you can at the palmetto + free shipping price. You will not be dissapointed.
