The M.A.S.S. (Mancraft Air Stock Support) stock is designed to provide air support for rifles and can accommodate a 13ci (0.21l) High-Pressure (HP) tank. Crafted from aluminum, the stock features a sleek black anodized finish, giving it a durable and visually appealing appearance. With a weight of approximately 400g (0.4kg / 0.9lb), it offers a balanced feel when mounted on the rifle.

One notable feature of the M.A.S.S. stock is its built-in pressure regulator called the Mancraft Modular Regulator (MMR). This regulator allows for consistent and adjustable air pressure delivery to the connected High-Pressure Air (HPA) engine. The stock’s compatibility extends to most HPA engines available in the market. The connection between the stock and the engine is established through a flexible pneumatic tube that runs inside the rifle’s body, ensuring a reliable and efficient air supply.

It’s important to note that the HPA tank itself is not included with the M.A.S.S. stock and must be purchased separately. This gives users the freedom to choose a tank that best suits their needs and preferences. The tank seen on the photo can be found in our shop.
