When I bought my Polytech M-14, the fellow who had the gun previously had taken and 'refinished' the stock.....so here is a 'military' rifle with a matte grey metal finish.....and the shiniest stock you ever did see!!!!
Not quite 'military' looking, if you know what I mean........
So I bought a surplus military stock that was kinda beat up....bunch of nicks, dings, ect. Also had the cut out for the full auto selector switch. No matter..I took a piece of walnut I had lying around and spliced it in to fill in the where the full auto switch went, then sanded it down so it was smooth. I then took and painted it flat olive drab (two coats) and let it dry completely. I then took and tore off long strips of masking tape (length-wise) and put them on the stock in a random fashion. I then took some of the camo paint I normally use on my duck boats and spray painted 'blotches' on the stock. I then removed the tape after the spray paint had dried; the result was a nice imitation of 'tiger stripe' camo.

Wanted to try this technique on one of my duck guns, but just haven't had the chance yet.
Kinda keepin' my eye out for another stock (gotta be at the right price, dontchaknow!

) so I can do the same thing, only in a snow camo pattern (i.e. spray paint it white!)
