Evolution Recon MK18 Mod 1 10.8” Carbontech Tan model: EC18AR-T

Hey i bought this Evolution Recon MK18 Mod 1 10.8” Carbontech Tan airsoft gun a few months ago from an online retailer for 400 dollars and thought I was going to get into airsofting, but I no longer have the time or money to get into a new hobby so the gun has been sitting in the box in my room and i have never even fired it. I dont have a battery for it, but i have everything that came in the box. A clip, the black muzzle cap, a power spring e120. Like i said i have never used the gun, never fired it. Brand new. With box.
