richard d on Jan 18, 2019

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.
Is it night vision as well?
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.

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

Frank P on Dec 9, 2018

How far can the red dot reach accurately for an ar15?
Scotty on Mar 23, 2019
BEST ANSWER: That’s a tough question as it varies in barrel length, size of target etc.
I can thump coyotes out to 200 without magnifiers in my 16” carbine. I can keep it on the head of a silhouette target at 100 with my 10.5”.

will this sight also mount on weaver base ?
john s on Jan 21, 2019
BEST ANSWER: I see no reason it will not. It’s the same design as most rails that mount any number of sights.
Should have asked an easier way. Will the romeo5 go on the AR-15 Freedom rifle without having to remove the front triangular iron sight. Will the romeo5 sit up high enough on the Freedom rifle top rail/MOE system?
Frank P on Dec 9, 2018
BEST ANSWER: Yup, the tall mount sits pretty high. Even clears the entire front sight hood on my Mp5.
will this fit on a P365?
Maury on Mar 25, 2019

Equal to or better than optics three time its price. Two thumbs up.
I have used a number of different Red Dot optics over the years. This sight is equal to or better than optics three times its price. It is accurate and so far holding a zero very well. I am happy with the purchase.

I am happy with it so far. Definitely a budget optic, but at least it isnt embarrassing to have on your rifle like a 30 dollar red dot.

Love the Romeo5
Like so many others, I am very impressed with this Red Dot Sight. Works perfect and does exactly as advertised. The motion activated light is a great feature. I would recommend this sight and will probably order another one for my next build.

Great deal! Get one now!
I would buy again. I have 3 of these. On an Ak47, Ar15, and keltec. Holds zero.after going to the range and about 100 rounds through each rifle. Have not yet tried a pistol though. I like the power saving settings and the res dot is visble on a sunny day at mid to high settings.

I like mine, I ordered a number of them, I have them mounted on my Daughters M&P 15, my 10.5" .300Blkout and presently on my Ruger MK IV Hunter, but I may move that one to something else.. I bought 5 total.

What a bargain
Such a great price on a quality red dot optic. Snap to install, clear and easy to identify, and love the variable brightness settings and that it shuts off after two minutes of inactivity to save battery life. Co-witnessed with my iron sights right out of the box. Highly good or better than others I've seen at twice the price.
