I try not to but I get a few ring marks and acope dings...even buying good rings and torqueing them as recommended they have slipped on heavy recoiling rifles...but mostly I tend to bump them and knock em around...so I don't worry about it much anymore...a scope is a tool that if used, will get a few "character flaws". I don't worry about resale value I'm gonna use it until it quits. You could just mask up the lens and paint it cammo or flat black alumahide from Brownells is pretty tough...My Vortex 4.5- 27x 56 HD Razor is pretty scratched up but it works just fine on my 6 dasher. The turrent knobs on the old Leupold mark 4 are hardly even anodized anymore as they were turned up and down for 20 plus years...dial and smile mode... but it still works and is now on the 50BMG.
