Three comments:
1.] IF you could find some ferns locally [ here on the Wet Coast we use CEDAR fronds ] lay them on your stock and spray a couple of darker colors over the fronds. Remove fronds, cover with three coats of Matte clear Urethane varnish for durability/UV resistance.
WALLA - easy to do instant camoflage that actually looks good, WITHOUT using an air brush, no artistic skill required.
2.] I have an AKM stock that is awaiting an appointment with Mr. Chopsaw for a shave.
The AKM stocks are IMHO, the best handling of the munimula stocks, because they balance better for me, and seem to have less weight forward [ less muzzle heavy ] than most. The Chop Mod variants are even better ... and of course, for perfect balance, no one in his right mind would use anything but a SHORTY M14 in his custom stock, right??.
Unfortuinately, all those rails just cry out for more things to clamp on to the stock .... like a brick or the kitchen sink. Use willpower, KISS, and don't bolt on any of those "tactical wannabe" add ons until the actual Zombie invasion ... when that 10,000,000 candlepower light will actually do some good.
Just as a side note, my AKM stock with YHM tubular butt stock weighs only a few ounces morer than one of my GI Fiberglass stocks made into the LAZ side folder.
And that is before the date with Mr Chopsaw.

3.] The Rooster cheek rest on your stock should be parallel to the bore, or slope the other way. Otherwise recoil will wedge that cheek rest into your cheekbone.
OUCH!!
