thats a vector SMG, in most games i played those are hit or miss. personally for me the rate of fire on those things are too quick which means you can empty a 30 round mag in 3 seconds flat which means if you take down 2 dudes in cod mobile then you have to reload and when your caught in the middle or reloading thats when an opponent player comes out of nowhere and laser beams you in the blink of an eye. for me i always liked snipers or slow firing smgs. maybe semi auto rifles that pack a punch like the SKS or m14 they have pretty powerful rounds. i guess if theres one sub machine gun i like it would be a mac 10 since they are old school.
