I’ll let form comment beyond that. Only 2 personal experiences I have:
-Slipped in 4” deep snow on wet leaves and fell with my full body weight onto the scope, so hard it knocked the wind out of me. I was worried I bent the barrel, let alone shifted zero on the scope. It was still perfectly zeroed when I checked.
-Had it in a pelican case flying between burlington VT, through chicago, through denver, to casper, wy. In chicago after boarding our plane I watched a baggage handler THROW the case from the cart onto the baggage conveyor, where it bounced out onto the runway, where he picked it up and more or less slammed it onto the conveyor. When we checked zero at destination it was perfectly zeroed still. It has also remained zero throughout the time I’ve owned it, a bit over 2 years.
