@ Rancho Relaxer: I´ve tried to implement your suggestions reggarding the foregrip and stock. I came to the conclusion that the folded stock looked better in the original version since i cant use the wood texture plus the stars and stripes pattern at once for one part. But i made a wooden texture for the foregrip and the solid stock. Here are the results:
