Scopwerks is run by Eric Sanders. His products are awesome. I run his side wheel, elevation knob and pointers on my Steyr LG110 FT. I also use his Scopeknob software to make my yardage and elevation tapes. He actually made a two piece side wheel for me. It makes stowing the rifle in my pelican case easier. Look at the 6 "side wheel for a March scope. That's my rifle in the picture. Eric is great to do business with. He helped me a lot by walking me through his Scopeknob software.
