Windham Weaponry has designed the Dissipator M4 to do what its name states. With a mid length gas system it will dissipate the gas transfer and significantly reduce recoil compared to a carine length gas system. The receiver is a flat top upper with a removable carry handle. It is constructed of forged 7075 T6 aircraft aluminum with a black hard coat anodized finish. The M4 profile 16 inch chrome lined barrel is finished off with the A2 flash suppressor. Sights included are rear A4 dual aperture and front A2 post. The Dissipator comes with a hard plastic gun case, black web sling, and operators manual. Windham is proud to warranty its rifles with a transferable lifetime warranty.
