Great value - SIG SAUER Romeo MSR 1x20 mm 2 MOA Dot Reflex Red Dot Sight

I’ve purchased many of these red-dot sights for different guns I have. I’ve been using them for years and they always work well. They’re very affordable and dependable. They don’t have options on the height of the sight but if you are using back-up sights on the gun it’s set up for the proper height. It’s a basic red-dot sight without any options for installation. The adjustment screws are exposed, while on other red-dot sights have caps on them but that never really bothered me. The battery lasts a long time and it’s easy to replace. It uses a coin type of battery but it’s a common size that a lot of stores sell. You can get that size of battery in drug stores or hardware stores. I really like this red-dot sight and they’re very affordable and dependable.
