Not bad, but the colors are not well suited for this weapon. Is that a olive green laser pointer on the shotgun? Doesn't really suit the weapon well, because you made the laser pointer a bit darker, and it's gonna be hard for some users to see their laser pointer on something they're aiming at, especially when they're in a dark place.
Check out the Assault Rifle CS-RC's laser pointer and it's colors. The laser pointer is a little bit bright, so you can see it clearly and better rather than a darkened laser pointer. For the magazine, it's colored a bit darker so it would suit it's real life counter part of the real weapon H&K XM8.
