Good to have another Uzi lover here.
Just one thing...
Anyone within ten minutes can accurately fire short bursts at a pie plate 100 yards away
Fixed it for you.
Even with +P+ ammo and/or a buffer to speed up the ROF and smooth out FA fire a bit, the bolt moving forward on the first shot is enough to throw off most peoples aim at 100 yards. It takes people used to a closed bolt gun a while to get used to that lurch on the first shot. In my experience anyway.
That said, I like a Uzi more than a MP5. The one bad thing I can say about Uzis is they are so dang heavy.
