I would rather have an M468 (Which I can't /cry) or an M4A1, with a grip, 30mm Red Dot sight, and maybe a flashlight.

I do have a MP7A1 with a 30mm Red Dot Sight (I have to say, they REALLY help, as I have never been a fan of iron sights) and it is pretty nice. No recoil at all.

I also have a replica BB gun version, so if I want to shoot it at friends I can do so without killing them, lol.
(Umarex, very well made replica with many metal parts.)
