The wait for reliable and affordable gas shotgun is over; featuring JAG Arms Scattergun Gas Shotgun Series. HDS Series features a solid stock design with rubber recoil pad for comfort. Full size stock also houses the green gas tank which can approximately hold 120 shots per fill (shot per fill will vary on weather, shooting practice and # of rounds per shot used). HDS series also features a more traditional pistol grip integrated with the full stock. Stock/grip is nicely matched by the full metal receiver which also houses the standard m1913 picattiny top rail to mount any optic. This shotgun features 3 barrels with fixed hop up which allows the users to switch from 3 rounds or 6 rounds per shot by a flick of a lever located inside the ejection port. Being gas powered, these shotguns are easier to pump compared to spring powered shotguns; Making the JAG Scattergun perfect for all ages. In addition, the realism in both operation and sound is unparalleled in gas shotguns.
