Great red dot sight - Holosun HS507C-X2 1x 2 MOA Dot Reflex Red Dot Sight

This sight is perfect for your G17/G19 or related RMR cut handgun. It works great, easy to dial in, the battery goes in the side without removing it in contrast to removing the whole site to change the battery. But it very rarely needs a battery because it's got solar (yup) and shake awake. I got the Vulcan site which is a great way to get on target when you draw or start from low hand or are just moving from target. I have several Holosuns and have no complaints (and with the price can afford to put one on everything). China company but great value for the money.
