M4 AEG Airsoft Rifle (with accessories) – Untested

For sale is an M4 AEG airsoft rifle, with accessories, originally purchased online for a Halloween outfit but never fired or used properly. It has been kept safe at home in a wardrobe for 10+ years. The rechargeable battery is located inside the front barrel. This gun *might* be working ok but I have been advised to list it as ‘untested’ and ‘for parts or not working’ just in case there are any potential issues. Any questions please feel free to ask, thanks for looking.
