I think camouflage on any gun looks ridiculous, I've heard many other gun people (never fudds, alot of them like it) express the same sentiments.
I've removed painted on camo that was actually pretty well done fro 2 different rifles. I was able to win the auctions cheap because of that paint.
One was a beautiful VZ 24 with monte carlo stock, .308 barrel, and a tasco scope and gorgeous bluing under the paint ($200). I've turned down $300+ offers for it on many occasions.
The other was a Norinco SKS, with a dragunov stock, 30 rd mag, 10rd aftermarket mag, scope mount, original receiver cover, and bipod. It was all painted a digital pattern "like the navy SEALs use" ($165). After I restore it to it's original condition it will be worth more than I paid for it and the parts will get auctioned off to someone that feels the compulsion to put the equivalent of curb feelers on a KISS rifle.
I've seen alot of camouflage tapes that can be removed and wouldn't decrease the guns value to ball but a niche market. That might be a better way to go.
Camo guns seem to be more popular with shotgunners though.
