i love your M4 with the Ithaca shotgun. Your Glock is awesome, also paint over the Orange parts or you will be lighted up in a woodland enviroment very easly.
But one of the most original M4's i've seen in a while. Most of the M4's i've seen resemble Dleta force or navy seals but yours truly stands out of the croud
Say if your fighting in a woddland enviroment, you want to paint your gun olive-drab or woodland camo because it will make you less visable. If you are fightingin a desert enviroment paint it tan or desert camo. Urban paint it gey,white or a light black
