I've got an great offer to buy an used Sightron SIII 6-24x50 mil/mil scope with exposed tactical turrets. I already have an SIII 8-32 with capped turrets on my BR gun that I feel offers very light resistance when adjusting. I'm worried that the exposed turrets of the 6-24 scope would accidently get turned out of zero when carried in the field on rough hunting tips. Anyone out there that have experience from the SIII exposed turrets and can give me some input about my concerns?
