Hey
@deermanok , Lew told me you ax'd this question. The short answer is, "Yes," the Romeo 5 is a fantastic little optic at a great price and tough as hell. It can also be coupled with one of their Juliet magnifiers, too, if you're into that sort of thing. That's the short answer. Now for the irritatingly pedantic explanation...
I am the Commandant of a Hard-Labor Camp for gear. I am HARD on my equipment. The two primary combat optics I have are EOTechs and Sig ROMEO5s. I am currently running Romeo5s on two 9mm sub-guns, an AKM, an AK74, a stock AR Carbine, and a hunting shotgun. I also have 5 in "stock" in my LaBORatory if I should break one, which I haven't been able to yet.
I cannot underline for you how much abuse these optics get. I run them in active shooter drills, building entry and clearing - where you basically ride the weapon's receiver up against door frames as you enter - rapid vehicle exits, extractions, movement drills, outside, inside, in mud, water, parking lots, - you get the picture: they get knocked around a lot.
These little SOBs just hold up.
They have a neat feature that shuts the optic down after 5 minutes of inactivity, but immediately reactivates it when the optic detects motion. It reactivates right back to where you had it set.
Great battery life.
it can mount close to the receiver for shotguns and low-sight plane long guns. It can also mount high to co-witness with AR sights.
Here it is mounted on a Commando 9mm Sub-Gun:
... and with BUS flipped up, with co-Witness...
Here is one mounted low on an AK-V
The only kinda issue is that, since it is a micro-dot, the field of view is not as good as on a holographic sight, like an EOTech, but I tend to mount them further back to accommodate that issue (as you can see in the pictures). Some will complain that mounting it that far back will interfere with your peripheral vision, which it can, but that hasn't been a problem for me. It's much easier to pick up a sight picture with the optic mounter further back, but different people will have different preferences.
Plus, for the price of one EOTech, you could get 4 ROMEO5s. I think I might tape one to my dog's head so I can see what he's pointed at...
I am not bagging on EOTechs. My EOTechs have happily accepted years of abuse. But they are better suited to rifles, where the added bulk will not be so noticeable. The EOTech is also better suited to an offensive weapon set up - there's no auto on/auto off feature like the Sig. The Sig is more geared toward an defensive scenario with the Auto On feature and easier movement due to it's smaller size. The Sig ROMEO5 is a just real little bastard of an optic.
That is all...
