The Advanced Modular Chassis System was designed by JP Enterprises to provide the ergonomics of the AR platform in a stock that fits a bolt gun. Machined from black anodized 6061 T6 aircraft-grade aluminum, the AMCS features a folding buttstock with an adjustable cheekpiece. The cheekpiece can be raised to allow the shooter to mount AR type optics or lowered to allow the use of standard height scope rings. The included pistol grip has a palm shelf. These features combine to provide linear recoil impulse and reduced muzzle rise. The JP Chassis system uses AICS pattern magazines (not included).
