I bought the mp7 once i started
the good points are that it fires alot of bullets and it fires them fast, its very light so you can run quite fast with it, and you can jump about and still keep a steady aim on your target, and of course, it looks pretty good
the bad points are that from a distance its USELESS even if your target isnt moving, another problem is that if your firing downwards on a target (such as from a ladder or from the top of some stairs) the aim can be very dodgy, dont ask me how i noticed this
OVERALL id say its like.. 6/10, so its not the best weapon and i wouldnt advise you to get it
PLEASE post and say what you think
