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.

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.

Absolutely awesome sight

Sweet little sight
Mounted on my 460V.
I have only about 8 shots through it with the sights attached. Stays solid so far. Heavy recoil, but supposedly it can take it.
We'll see as I shoot it more.

Great red dot, great price
For $119, this optic is a steal. Its sturdy, it mounts easily and looks great. In no way is this a cheap feeling optic. All metal, sleek look, sturdy feel.
If you're up in the air about a red dot (especially a first time buyer), have no fear with this purchase. You'll be very happy.
