Anyone unlocked this yet? Is it any good?

i have, and its awesome, probably my favorite gun, its way better then the grendal

I personally like the look of the scar the most, although the Scarab is the better combat catalyst.

the scarab is a ACR i think like the one in homefront and mw2

The scarab is rediculously good but the scar still over powers it although the stats show differently the game play shows it
