The world renowned team over at SIG SAUER dipped their hands into the airsoft market to produce an extremely accurate M18 replica. Constructed from a full metal top slide and polymer grip, this airsoft replica not only looks and feels authentic; it’s almost as durable as its real-steel counterpart. Military forces around the world rely on SIG SAUER to produce well made firearms worth trusting in combat situations, and SIG SAUER has met that demand since the mid 1800s. This M18 replica features realistic blowback action for added authenticity and realism during training sessions. Serrations along the front and rear of the functional slide provides optimal grip for users to manually cock a BB into the firing chamber, or to give access to the hop-up chamber. Players can utilize the adjustable hop-up to account for various BB weight and target range for the most accurate shot every time. This airsoft replica has many features that match the real M18, including the ability to be quickly field stripped for maintenance or cleaning. The universal design of the M18 allows both Green Gas and Co2 magazines to be used, but this version comes with a Green Gas magazine. A small 20mm picatinny rail section along the bottom of the barrel can house a wide range of tactical accessories including flash lights or lasers. The polymer grip is ergonomically designed to provide optimal stability and comfort when taking aim or hastily changing positions. Front and rear iron sights allow users to quickly and accurately zero in their targets without the need for an additional optic accessory. Green Gas or propane powers this airsoft replica, which is filled directly into the 21 round magazine. If authenticity and reliability are what you look for when choosing your next sidearm, then the M18 from SIG SAUER may be the perfect choice for you.
