Thread: securing scope dial caps in the bush or transport - how?

So its happened to me twice now. Pull the rifle out if its case to find the scope dials are way way gone from zero..... Both times I've had to guess that the caps have lifted up and turned without actually moving the dial..... But it certainly knocks the confidence and I'm keen on finding a useful way of stopping this from happening. The weaver 2-10 caps can lift up and "freewheel".

I'm wondering about strips of rubber around the turrets vertically, so it wraps around both caps and the scope body. Shouldn't bother bolt cycling?

But before I go and reinvent this wheel - I'm guessing the forum guru's have already solved this one?

Thanks in advance
