I'm no professional but I've screwed up a few stocks, so here's what I learned.
- fill in the selector cut-out with JB Weld or any other epoxy type putty, the two part ones in a long cylindrical tube, Devcon is supposed to be very good. Add some sort of support inside the cut-out area, a stainless screw is what I use.
- while you have the putty out you might also want to bed the action. It's kind of hard to explain but there should be a sticky on it somewhere.
- re-inforcing the front forearm is optional but something I do, as has been said leave room for the gas system.
- I blasted the brown paint that the stock came with off, I don't really know if it matter though, I just figure get down to the base material before painting.
- If you want a textured finish use the truck bedliner in a can from Can. Tire. I've tried other textured paints but they're not as hard.
- Krylon paint are fine as are the camo paints you can get in a can at Can. Tire but you should put a coat of matte clear over them. Overall though they're not extremely durable.
- If you want a paint that will harden go for Gun Kote (available from V-Bull, check the banners at the top of the site). Get the air cure stuff, if doing camo patterns finish off with their matte clear coat. DO NOT use the bake on Gun Kote paints, the heat will expand the foam inside your stock and split it in two, don't ask how I know this! Also the guys at Gun Kote will answer any questions you have, great people when you need some help.
- Get a cheap air brush ($35), it'll do a better job than a brush or spray can. They're easy to use, took me about 10min. to figure it out and it gives you great control.
Otherwise it's not too hard to do, just requires some patience and time. Go slow and things will work out great. Good luck.
