I've had a scope break. Mounts come loose. Swivel studs break. Sights come loose. Once I slipped on ice and filled the bore with so much snow, I had to hike back to camp to rectify. Had oil gel up optic adjustments and even a bolt once in sub- zero temps. Good to double check the bore for obstruction after bad weather or falls.

Some of the above can be attributed to operator error. Didn't have the internet to warn me. Had to learn on my own.

All things considered. I've been fortunate. Nothing ever completely stopped a hunt.
