I got my Mp7 last month and just love the thing and plan on fielding it at outdoor games for the summer.
Question to the developers - Any hints as to the ETA for the HPV kit? Will there be a TBB longer than 160mm?
Regarding the accuracy, I can easily hit a human target at 100+ feet.
IMO, you get your money's worth with this barrel. So long as you are not hampered by CQB FPS restrictions I think it's a good investment.
PS: What I would really like to put in is an High Power Bolt. If you read Radix's post earlier on in this thread you'll understand why. For me this gun is all about power to reach out far in a small package. So far it's doing that very well.
