Only used once. Excellent condition can include some BBs and a chest rig. 

The weapon features a Mock KeyMod Style Rail, which comes with a full top-length 20mm RIS / RAS Rail, allowing you to attach a variety of sights and scopes to the weapon, giving plenty of customization options. The weapon also has two front side rails designed for Torches, Lights and Lasers as well as a front bottom rail for Grips and Bi-pods. The body of the weapon features a functional mock charging handle which is used to expose the hop-up for the weapon, allowing the amount of spin placed on the BB to be adjusted giving the gun a longer range. The weapon features a multi-position stock which can be adjusted to accommodate for different height users, and features a rear sling plate, allowing a variety of slings to hold your gun should it be dropped or to free up both hands for activities. The Stock is of a 'Crane' Design, allowing a battery of up to 9.6v NiMH Crane Battery to be added, giving plenty of power and lifetime.  This weapon is great as it accepts a variety of STANAG based Airsoft Magazine, making it easy to buy spare magazine. This is the perfect weapon for any Beginner Airsoft Player, or for those who just simply want to shoot in their back garden.
