Pick it. Click it. Stick it! Patented Accu-Clicks make this state-of-the-art single pin slider sight function like a multi-pin sight. Set each Accu-Click at a specific distance (i.e. 20yards, 30 yards, etc.) so that the slider will stop where you want it. Simply “Pick” your distance, “Click” it into place, and “Stick” your target! The Accutouch also features a superior windage dovetail guide system that provides zero backlash. This means that when you are adjusting and switch directions, the sight almost immediately moves the opposite direction. Some other sights have so much backlash, it takes three clicks or more to start moving in the opposite direction.
