I have a bunch of ARD's and scope covers; favorite designs are Tenebraex and John Aadland's.
I would like to see a hybrid of their design concepts wherein one does not need to screw the ARD into the scope threads that usually
accommodate sunscreen extensions etc.
The camera industry seems to already be the tip of the spear in their innovations (kind of like RRS was that cross-decked to firearms) , specifically employing magnets to hold open the lens caps / inserted lens filters etc. The last image posted illustrates the magnetic pairing to secure the lens covers.
I don't care for the elastic retainers your covers employ and it seems in one of your images when the ARD is displaced upward from the scope (which only has one option of final position due to the elastic retention cords) it impedes or potentially obstructs the line-of-sight of the secondary red dot optic mounted rearward.
I would like to retain the versatility of the Tenebraex design wherein the scope cover can be rotated and indexed to desired out-of-the-way position with the outer lobes of the ring.
I would like to see a system that allows the protective scope cover allowed to be rotated outward in user preferred 360 degrees options.
The integrated ARD would likewise be allowed to rotate outward, the ARD being secured in place to the scope cover via magnetics, so there is no flopping about of the two components. That would allow the user to quickly choose whether the ARD was useful or not, as they typically depreciate ~10-15% of the light gathering ability of the scope optics.
I find that Aadlands set screw securing the caps to the scope is the most robust system.
