UTGParallax Index Wheel for OP3 Scopes, 80mm Diameter

Fit is snug. No need for set screws. Helps making adjustment easier to turn. Double check clearances if your magazine loads on the left side. I was able to put both mounts behind the breach on a piccitiney rail using a compact UTG OP3 scope. Plenty of clearance.

I got the Side Wheel (SW), to my surprise there is no way to secure the SW on the Knob, it just pushes on. I move around a lot when shooting varmints, thinking it might not stay in place.Pros:Looks good, appears to be good quality.Easy mounting, press fit.Cons:No way to secure the SW to the Scope Knob.We will see how it works out, problem will be if I can get it tested before my RETURN TIME runs out !Not really happy with the idea of no way to secure it to the scope.

I always wanted a bigger focusing wheels on this scope. This UTG Parallax Index Wheel for OP3 Scopes works fine on my scope, but I do have to remove it to insert my pellet magazine. Afterwards, the Wheel easily slips back on the focusing knob, and the bumps on the focusing knob align with indentations on the Wheel's rubbery inner surface so that everything is properly positioned.

This wheel is specifically made for the UTG OP3 scopes. The internal hard foam liner will not fit any of the other UTG scopes. Would like to see it in 100mm as well as the 80 mm. Well made product for a very fair price.
