airsoft polarstar jack G&P M4 gun

Description

The base is a G&P M4 with a polarstar Jack on the inside. Works fine only noticeable thing is that there is a missing bolt catcher as shown in pictures, and a little rust on the air hose.
FPS is currently at 360 with 25g (can be adjusted of course)
RPS is running at 20 so pretty high.
I am not sure of the exact range since I live in a suburb now.
Comes with all shown in picture: gun, tank, scope, g&p 120rnd magazine, and battery (wired to deans)
