All the modes.
I got this when I got my Impulse its sweet its got four fireing modes and sweet de bounce and all the kick in modes and that crap. its nice to put in becaus you get use to taking your grip apart. Over all just a sweet up for a gun.
Like i said sweet up im not going to tell you to get it becaus its a lot of mony for a bord but its sweet.
