i'm looking to trade for an m4, maybe even an m16.

this mp5 works perfectly!

comes with:
2 hi-cap magazines
JG blue high torque motor
shims
re-greased
two large type batteries
1 large type charger

if you are trading me an M4, i will throw in a large-to-small tamiya connector and a small type battery.

also, this gun is EXTREMELY easy to disassemble. 2 pins and you're done, 4 screws as per usual to take out the motor.

mp5 sold... i have an A&K SVD with scope mount, Bipod, and sling, upgraded piston and cylinder, and m150 spring that I could also trade for said M4/M16

let me know.
