Pros:

-made me play L4D2 from a 2 month non playing spree
-It is epic , i deleted all my M16 replacements and left only this
-looks great with BLR survivors
-prefect new reload animation and firing sound

Cons:

-finger not correctly placed on the trigger
-flashlight is upside down, noticable on custom flashlights,my chuck norris flashlight does NOT approve

Conclusion:

Great gun, no bugs exept finger and flashlight (IF you use default than you wont even notice it) and those are minor bugs , no big bugs like clipping, hand trough gun *ermgraneadelauncherm4a1moderm* and even missing laser *ermblackops2remingtonerm*. if you like futuristic guns , stop searching , this is your thing
