I jsut recently got a new Echo 1 MP5 PDW...there is nothing wrong with it Iwas just wondering what the little screw on the bottom of the handle is. After a recent match I noticed that the screw was out farther than normal and so I used my finger and screwed it back in towards the motor. I was just wondering if anyone could tell me what its purpose is? Thanks.

It holds the motor and handle tight together.
That screw screws into the motor.
Put a piece of electrical tape over it.

Now if you do loose it it isn't that bad but... make sure you don't loose the rest of the screws on other parts of the thug ass spray n pray MACHINE!!! WHHOOOO!!!!!

BTW why don't any manufacturers make vikers, maxim, etc WWI airsoft machinegun replicas?????????????????????????????????????????????????????
