Fantastic gun. amazing rate of fire. build quality externally is spot on.
...internals... well lets just say i got a lemon?
One reason you may want to think twice about an MP9,
This is after 8 mags of regular use. nothing special. room temperature about 15-20 celcius. half way through the 9th mag, the gun stopped feeding and did not cycle properly. after proper take down, this is the horror!
I question the durability of this part.. it is not very robust for a high-cycle gbb smg
Sorry for any broken pipe dreams...
