The Sig Sauer Romeo 4M runs on a single CR2032 battery and can be changed out in seconds because of the side mounted battery compartment. This Sig red dot sight is rated IPX-8 waterproof and fog proof which means it can be submerged under water greater than three feet and still function. With a CNC machined aluminum body, this optic is extremely durable and can withstand multiple impacts without losing zero. The grey coating and trapezoidal surface design help to break up light and prevent reflections that can give away your position. The objective is also Mil-Spec coated to ensure optimal light transmission and is designed to reduce reflective glare that can also give away your position.
This red dot sight is the perfect for your AR-15 or similar rifle and it even comes with two picatinny mounts, so you can attach it directly to your rifle right out of the box. With one high mount and one low mount, you can run it as low as possible or with iron sights. Pair this red dot sight with a magnifier and you have yourself an extremely capable set up for target shooting, home defense, or hunting.

Great red dot with an excellent reticle
by No one -
I purchased this for a clone build of a Federal agency upper. I understand that the 4M was used for a couple of years as an approved optic, so I picked this up and was not dissapointed. The dot is very crisp, and the Eotech type reticle is great. The brightness can be turned way down to what almost seems like a faint dot that is maybe one moa, all the way up to very bright. The controls are very distinct in feel, and the lens caps work well. I don't know how the front lens cap works with the kill flash though, so I left the kill flash off. It is also a long sight on the rail, longer than my Primary Arms push button micro dot with mount, so I was able to mount a buis, but not a buis and magnifier.Also It is a absolute cowitness mount. I am really impressed, compared to a other red dot optics I have this is a great value and seems on par with the higher end stuff.<br>It is really nice being able to switch between the circle dot and dot, it is really great to be able to do that.
Have this unit in a 300 BLK SBR and like it a lot. Dot is clear, and the reticle options are nice. Minor complaint is that you can't use the front cap if you're using the kill-flash, so it's either one or the other. On the bad side, the mounting screw is rather weak and easy to break. Already got a replacement screw from Sig Sauer.
<br>Plus: Crisp dot, controls, reticle options, killflash included
<br>Minus: mutually exclusive killflash and front lens cover, weak mounting screw
<br>Overall, a very good optic for the price!

These are great red dots. The redical is fantastic and provides a lot of flexibility. For the money this is a great value.
