The G&G Full Metal TR16 A3 Blowback AEG Airsoft Gun is a great option for the M16 lovers out there. It is part of G&G’s Top Tech line, meaning it features a full metal body, and their famous pneumatic blowback system, making the gun both look and feel very realistic during use. Every part that would be metal on a real M16 is metal on the TR16, just as every part that would be polymer is such. The carry handle is removable, exposing a tactical rail segment that is perfect for the addition of your favorite optics, and when retracted, the functioning charging handle allows access to the hop up adjustment. Overall, the G&G Full Metal TR16 A3 Blowback AEG Airsoft Gun is a great new addition to G&G’s already impressive lineup of M16 airsoft guns.
