Pros:

-Good sound mods
-CELL camo (As always... Very cool!!)
-Hologram scope looks cool
-Simple and clear reload animation

Cons:

-Reload animation and actual reload time is slightly off (About less than 1 sec of delay)

Conclusion:

Very nice replacement for SCAR. 
Definitely worth the download.
Just watch the ammo numbers instead of the reload animation during the reload, or you might end up still in reloading while the reload animation has finished
