I have for sale a G&G UMP.
It's about four years old, and was well treated by its two previous owners.
It is in good condition, the only noticeable mar is that the magazine was slightly externally damaged by heat.
Included will be the gun, mag, and battery with charger if so desired.
I am asking $300 obo, I will accept reasonable trades.
