I don't know about you guys but the side parallax knob on my two Athlon Talos 4-14x44 scope are very hard to turn. I can't find any side wheel add on to make adjustment easier. I remember someone saying they used a UTG side wheel and it worked for them. I have some UTG scopes and like using the smaller 60mm diameter side wheel as sometimes the UTG scopes have stiff side parallax wheels too. This can be a problem in the field hunting when you have your gun shouldered and trying to focus your scope with one hand. Anyway the UTG side wheel is made to fit into the the indents on the side parallax knob and then the two set screw push the interior side wheel rubber ring tight to hold. This arrangement won't work with the very tight side parallax knobs on my Talos scopes. I ended up replacing the two shorter metric set screws with two longer ones about 1/2" long. These go all the way through the rubber ring and engage the side knob. This solution has seemed to work. The video shows what I did and although I make a few mistakes on words spoke the just of what I did comes across. Bill
