-has 40 rounds, uses drum ammo similar look to that on Vance's 9mm.
-reduced rate of fire, slightly less spread
-utilises the larger 5.56 ammo, increased critical rate
sort of like an alternative to the light MG but with more mobility and precision at the cost of ammo quantity.
Also a unique silenced .22 SMG;
-extended barrel and fore grip
-significantly reduced spread and improved range
-much better sneak attack criticals
So it performs like an AR with it's range with low damage so the idea being you can shower the enemy from range and remain hidden too with a high enough sneak rating.
