You should look into getting it hydrodipped if you're still looking.
All those mossy oak/real tree patterns among hundreds of others are all available and can be put onto your XCR. There's thousands of patterns if you are interested in something besides camo too. One more cool thing is you can "tweak" a lot of patterns by changing the base coat. Lots of the films have transparent spots or patterns (paint free) so your base coat stands out through them. We have a white and black camo that is 1/3 transparent and it seems to work well with most colours, as an example.
If you don't shoot it until the barrel is red hot you can even do the barrel, most of it holds up to heat very well! (Some people do the down pipes to their turbos... I can't say if I'd recommend this at this time.)
