If you want to add some color to your wood, I have had good luck using leather dye. It goes on dark but you just use 4 ought steel wool to buff it back to the depth of color that you want. You can also dilute it to give an even lighter color. Just buff with the steel wool until you have the color that you want. For the final finish, I like to use Birchwood-Casey's stock finish, Tru Oil or Linspeed. Apply extremely light coats with your finger tips, rub in thoroughly and allow each coat to dry over night. then buff with 4 ought steel wool just enough to remove the shine. Not too hard or you will remove the finish. It is very thin at this point. Keep applying additional coats in this manner, allowing each to dry for 24 hours, until you have applied around 10 or 12 coats. Now, let it sit in a nice dry place to cure for a few days (about a week) and then lightly buff with the 4 ought steel wool to the soft sheen that you like. Now, you can use the gun if you wish but if you can stand the wait, let the stock sit in your nice dry place to cure for about a month. Then use a product called Stock Sheen. It, too, is a Birchwood-Casey product. It has waxes and extremely fine abrasives in it. Use it as directed and you will end up with a gorgeous stock finish that will resemble or exceed the one in your pictures.
