Pros:

-Very detailed
-All the attachments give off the placebo effect of the gun being more powerful

Cons:

-No new icon
-World model sticks into the floor
-Muzzle flash appears halfway through the silencer
-Default animations
-Strange hand movements after melee animation is finished

Conclusion:

Generally it's a great gun, but there are still issues that need to be addressed. Also I'd love to see a version that uses the animations from Doktor Haus'  M16A2 Reborn mod.
