Rifle Scopes US Optics EREK Knob

Re: US Optics EREK Knob

The EREK knob is great for making fast and/or massive corrections. Watch the Youtube video like stated, or contact USO if it still doesn't make any sense for an instruction manual. The most difficult part is setting up the zero with the set screw, everything else is easy.
