This is a custom made m4 type of rifle made by Airsoft GI. It is made with G and G Airsoft materials. It is an incredible gun. I only used it a handful of times, it is practically new. I spent a fortune on it but shortly after stopped airsofting due to me getting older and being busy. It’s such a lightweight, easily usable, accurate, and reliable gun. I wish I didn’t have to sell it I just don’t use it anymore. Also a really cool looking weapon. Airsoft GI did an awesome job with this custom gun. Also comes with a neat little red dot sight that you can alter with the turn of a switch. (Also comes with battery pack)
