Parallax Wheel for an Airgun Scope Element Helix

I ended up with this design because I tried a number of the ones available that left me underwhelmed. This wheel is 5.5" dia. I already have a nautilus style, wanted to try a round one for Field Target. If you make small scale adjustments with the adapter you can really dial in the fit. I used a nylock 3mm nut and a socket cap screw on the wheel and regular 2.5mm hardware on the pointer (which is for a 30mm scope tube). I really like the way it holds but I have an idea for a hub cap center for this that will push clamp load over the scope turret even more, and allow for some graphic expression as well. If you like it, hit that donate button and send a few bucks my way, it will be greatly appreciated, but never required. Enjoy!
