This Airsoft Replica is constructed entirely from Polymer, and is extremely lightweight, making it great for a funny Sidearm, or for Backyard Plinking. The shotgun features an externally adjustable hop-up unit, designed to add spin to the BBs for range and accuracy, and can be adjusted to suit BBs up to a weight of 0.25g. The top of the shotgun features a 20mm RIS / RAS Rail designed to allow attachments such as Red Dot and Holographic Sights. The shotgun is loaded via a magazine system, with each magazine holding up to 20 rounds, and are each loaded either by hand or with an Airsoft Speed Loader. This shotgun is perfect for those Airsoft Skirmishers looking for a Humiliation Gun, or for those looking for a simple backyard plinker. Please note that this is an extremely budget gun, and as such it is great for a bit of fun, but not for serious skirmishing. These are great for humiliation guns or back garden plinking.
