The competition series UMP offers high performance and reliability for an affordable price. This fully automatic electric airsoft gun features fully licensed H&K trademarks and is a 1:1 scale replica of the real gun. The gun is made of a durable ABS plastic which makes the gun tough and lightweight. This gun is designed for CQB play. The stock can be folded to the side for a more compact profile, making this AEG perfect for CQB skirmishes. It shoots right around 330 FPS making it legal to use at most CQB fields. It also has a quick change spring system, allowing the user to easily increase the FPS without having to disassemble the whole gun. This makes the gun a viable option for field play as well. The included high capacity magazine can hold 400 rounds for continuous shooting and less frequent reloads. An 8.4v rechargeable NiMH battery and charger are included. This gun has a 60 day warranty through UMAREX USA.
