Samurai the mp7 would be GBB and the others are shorter still than my 417 350c so their an improvement the reloading and switching from semi to autos not that's important anyway
The guns are mainly for quick paced games where my weighty rifles to heavy and slows me down
Also where can I get a GBB Tm mp7 jcheese and how do you have to run them on propane or will green gas do
Basically pros and cons
