MTC Optics Side Focus Wheel
The MTC Optics Large 3″ Side Focus Wheel is specifically designed for mounting to MTC Scopes (Mamba Pro, Viper Pro). It attaches in seconds using using an ingenious compression type collar. Simply slip on and tighten the 3 outer screws (you may need to loosen the 3 screws first).
NOTE: IT SHOULD NOT BE USED ON HIGH RECOIL RIFLES AS THE INERTIA CAN DAMAGE THE PARALLAX TURRET
The large side focus wheel is designed as a focusing aid and will come with pre-printed numbers that align with the parallax turret on the 5-30 model of scopes only. The numbers are for approximation only and not for effective range finding.
If you wish to carry out basic range finding at close distances, or wish to use the wheel on other magnification models, you will need to create a custom ranging tape to apply over the wheel.
See an example of a custom side focus tape for the Viper Pro 3-18×50 by clicking here.
For best results to create a custom tape based on your own eye prescription, first set the dipoter (if you have not done so already) for optimum reticle focus. Apply a blank tape (car detailing tape works well) and mark out your own ranges.
NOTE: ALWAYS FOCUS FROM THE SAME DIRECTION (INFINITY INWARDS OR CLOSE TO OUTWARDS). IF YOU GO BEYOND FOCUS, REVERSE THE WHEEL AND RE-APPROACH THE TARGET FROM THE SAME DIRECTION
