Typical trijicon excellence - Trijicon MRO 1x25 mm 2 MOA Reticle Red Dot Sight

I mounted this to my new Sig MPX. I wanted a red dot that would help with quick target acquisition and transition, and the 25mm lens is great in that regard. I have an Aimpoint Micro on one of my ARs, and while nice, it's a noticeably smaller window than the MRO. The view is crystal clear like every Trijicon I've used, and the dot is very crisp. I think it'd be fine on a rifle even for long shots, you wouldn't have to worry about a blurry dot throwing off your aim at longer, un-magnified, distances. The brightness has a wide variety of adjustments from not-visible-in-daylight to blazing. I haven't had it long enough to tell you if the battery will last for years while left on, but it's nice to know that it's designed that way. If it lasted even a single year while left on continuously that'd be pretty great, let alone five years. It's expensive, but good optics are typically worth it. Trijicon has made a name for being virtually indestructible, so combine that with perfect optical quality and $400-$500 doesn't seem so bad. Their customer service has always been great, in my experience, which is worth a lot if you ever have a problem If you're considering a red dot for a rifle or sub-gun, this is a great choice. It's a little larger than a Micro, but the view is substantially better.
