Great clarity and brightness, but watch the battery life - Bushnell Trophy TRS 1x25mm 3 MOA Red Dot Sight

I've had one of these for about two years now and have yet to be dissatisfied with this red dot. It is no Aimpoint, surely, but it is still a good purchase that will get you a good optic for the occasional-use rifle or even a duty weapon. I purchased one of these before the mount-included versions were available in my area, so I purchased an Alamo Four Star mount for it to cowitness with AR-15 iron sights. This combination is phenomenal. Battery life is not exactly impressive, and I've had a few instances at the range where I realized I accidentally left it on a few days before, so just be sure of your power settings.
