The weapon is powered by an Electric Gearbox, which uses Batteries for power allowing the rifle to fire on both Semi-Automatic and Fully Automatic. The weapon features an Adjustable Hop-Up system which is designed to add Spin to the BB to improve the rifles Range and Accuracy, and is fully adjustable for use with a wide range of BB Weights. The weapon's battery is stored in the Handguard, which is easy to remove by pulling back on the Delta Ring to slide out the lower half. The Stock is fully adjustable so it can be adjusted to the users size, making it comfy for a wide range of users. The top carry handle can be removed to reveal a standard 20mm RIS / RAS Rail, the most common in Airsoft, allowing access to a wide variety of aftermarket Sights and Scopes. The gun comes supplied with a Magazine, which is a High Capacity STANAG Style magazine, giving the option of a wide range of Magazine Types, holds up to 450rnds, and is wound from the bottom using the Winding Wheel. This rifle is perfect for those Airsoft Skirmishers who are looking for the perfect starter rifle, with great build quality and plenty of room for upgrades and attachments to make the rifle their own.
