With a bright, easy-to-acquire dot and unlimited eye relief, the Buck Mark Pro Red Dot Sight is a great addition to your turkey shotgun, rimfire plinker or even a centerfire rifle. This compact sight is built tough with a sturdy housing made from lightweight aluminum and protected with a flexible armor coating. The 3 MOA dot is fine enough for accuracy at extended distances and ideal for close quarters in the deep woods. The dot features three brightness settings that allow you to adapt to your lighting conditions. Battery life is approximately 240 hours on the medium setting. This sight attaches easily to a Picatinny-style rail using the included, low height base. If a taller base is needed, the Buck Mark Pro uses the Aimpoint Micro style mounting pattern that is very common among red dot users. Mounting tools, a lens cloth and protective shipping/storage box are included.
