I'm with jnk556....
Rit dye (the dry kind, not in the bottles) works great for me in several applications...
I use the scarlet, and brown, and orange....the orange gives it a bit of that iodine-y color...
Get a few coffee filters, put into the mouth of like a ball jar, dump the dry dye pack in, and pour in rubbing alcohol, and let drip through, it will pull the dye out, and leave behind the salt in the mix....continue to slowly drip the alcohol through until the dye is all in the jar...you can do one for each color, then mix until you get the color you desire.
The nice thing about dye is it penetrates the wood, as opposed to laying on the surface like stain....let it dry really well, you can layer coats to get the depth of color you want...
I would then take the AK furniture and hang it, and mist coat Minwax Spray Poly, semi-gloss...the furniture would come out looking very much like real Russain AK furniture...I bet it would work well for a Mosin stock...
When I built my AK-74, I spent the big bucks and ordered a NOS complete Russian original AK-74 wood set from Tantal (Doug Ford) before he died. He always had amazing stuff, and a fantastic web site...the coolest thing is it came with an original 74 laminated pistol grip, not bakelite...so freakin' nice, I never even shoot it....
