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.

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.

will this work with the Echo 1 thermal?
Goose on Oct 16, 2018
BEST ANSWER: The Echo 1 is designed to be used with both eyes opened, like any reflex sight. This allows you to have a wide field of view, with a clear peripheral vision. The small device has a 30 hz refresh rate which is perfect for the non-magnified optic. This makes it easy to track targets and aim rapidly. The unit has a close focus distance of 1 meter. The optic weighs a mere 14.7 ounces and is only 4.3 inches long.
How sharp of a dot is the reticle? The one I received seems to look more starish than expected.
Uriah H on Oct 9, 2018
BEST ANSWER: If you have astigmatism, the dot may starburst or appear blurry. This would happen with other sights as well. Did you try both eyes? Also try turning brightness down.

bradley on Sep 12, 2018

Willy on Jul 27, 2018
BEST ANSWER: If you've got the top bolt on rail you install the Red Dot with the included low mount and it will work perfectly.

Excellent sight. Superior quality and fuctionality.
I absolutely love it. In my opinion it's a LOT BETTER than Vortex or many other red dot sights that cost much more. Light transmission is great. No "fish eye" effect like in a Vortex.
I love the motion activated red dot. No need to turn it on or off. Simply pick up the gun and it's ready to go.
I've been tempted to buy another one.

great redot for tactical 12 gauge shotgun
Very impressed with this Romeo5 1x20 red dot, especially the automatic on feature when weapon is picked up. Nothing like being ready for that bump in the night with speed on your side. I have not shot many rounds yet through this scope but I hope it will hang, time will tell. Would recommend as the price alone for such a piece of equipment is worth it alone. Fast shipping and great company to deal with.
