Zeroing block ZB Lite is a universal mounting base that allows you to mount a variety of accessories to a gun weaver base, and allows you to change the elevation and windage to zero it . Zeroing is effortlessly done with traditional feel rifle scope turrets, which can be used with ease at any time and without any special tools. It can zero a range of devices such as laser sights, illuminators, laser range-finding modules, telescopic sights and red dot sights. Additionally, it can be used to increase the elevation of a generic rifle scope, for shooters that need to cover targets close up to them.
