You should go with a gas or electric MP7, PDW, or an AK74U version. Best 3 small autos in my opinion. If you want something to go with your bad ass setup there Mike, go with the gas MP7. Sounds and feels wicked. Scares the shit out of a lot of people too. For a gas gun it's on the more inexpensive side as well, but if you don't want the gas version, the AEG versions are still a good pick. P90s are cool, but trying to get good mags at a decent price for them is a pain in the ass.
