I am not hatin' but there are some various things you could fix.
The Auto Carbines are pretty cool, but I think the first one could have a better reload.
I don't like the AKM-47 reloading sounds, or the firing sounds. This includes the Stockless too. I like the firing sound for the Silenced, but there should less muzzle flash. The Thompson uses ammo wayyyy too fast. I also don't like the reload sounds for the Thompson. The shooting sounds like something from the TF2 Pistol. The M16 sounds perfect, but it is way too thin, and so are the sights. Deagle sounds Badass, except the reloading. The Colts fire sound is ok.
Other then that these look good.
