My pink and black laminate 10/22:
Bought it strictly as a plinking gun so figured I would get a weird colour. I get all kinds of comments like "I think you brought your moms gun to the range" and "you do know your rifle is pink, right?" I guess it is kinda odd when a 6'3" 260lbs man has a little pink rifle. I have have a hot pink soft case to match
Not rimfire but my No.1 Mk.3 Lee Enfield prior to it's ATI monte carlo stock. My friend dared me to paint it pink while I was waiting for the ATI stock from Cabelas so I did. Not the best job but was just for a dare anyway.
For those of you worried about ruining a classic it was in horrible shape and was already sporterized. I got it for under $100 and the bore is pitted and shot out; the last 2" of the barrel has no visible rifling at all in it. I can somehow still get ~3" at 50 yards with it though.
