Fully licensed "Tactical Tuna" or the FN Herstal F2000 AEG from Cybergun is available at Evike.com and Matt tells more about the details in this video review. This is made with a high-strength nylon polymer body and since it is licensed, it comes with authentic FN Herstal trademarks and logos. The reinforced gearbox is full metal with high strength steel gears. It has metal flat top rail for easy scope mounting and also has adjustable front & rear sights. Other features are a integrated rear sling loop and a fully ambidextrous operation.
