Yeah, welcome to the forum. I gave some ideas over on your other thread with exactly the same question. Again, not nearly enough information in the original question, but a little Googling around should help you narrow your choices.
I'm lookin for something that would replace my factory stOck, it has a synthetic on there now, I would like to put another synthetic on thier but that is mossy oak camo or real tree camo with a pistol grip cause is it gonna be my new hunting rifle.
