Pros:

A high Minecraft Resembalance
Mainly fit into both MC and default hand textures

Cons:

M60 (general), Military Sniper (sight), M16 (top rail), Chrome shotgun (iron sights) and the magnum (barrel) Should be made slightly smaller as i feel the block the user's view quite a bit.

Conclusion:

A very well Made Mod (9.5 due to sizes being a bit big) i would recommend this for playing on deathcraft or if you are just a big minecraft fan :)
