Just for clarity, this is in addition to the factory knobs, not a replacement.
You have to drill holes for this, the pictures show the high position.
The screen is now rock solid.
To use this instead of the knobs, the factory mount has nuts welded to it on the inside which may have to be drilled, if they are 5mm or less.
Sunny,
Just to clarify, you "drilled a 5mm hole in each side of the mount" which are hidden in your photos; could you post photos without the QD axle installed. It would appear that in the lowest position the QD axle would interfere with the OEM adjustment knobs, and thus the low position cannot be utilized. Is this correct, and if not could you explain how and show in more photos how it all works in each position please? Also, did you not utilize the QD axles serrated clamp rings and if you removed them, how? I would presume when you do change the shield positions you need only flip the QD axle clamp lever, loosen the OEM knobs, re-position the shield, and flip the QD axle clamp lever back to tighten the axle, correct?
Thanks
