Pros:

They look great, and make me want to have those things in Minecraft.

Cons:

The Pump Shotgun, SMG, Silenced SMG, Combat Shotgun, and Sniper Rifle are missing textures for me. 

Conclusion:

I love the guns that have textures, and luckily I don't really like any of the guns missing textures (except the sniper and silenced SMG. Overall, good mod, just needs some work.
