In barrier pack systems, the propellant is physically separated from the product concentrate. The propellant pressure on the outside of the barrier serves only to push the contents from the container. In the piston type system, a polyethylene piston is fitted into the container.
Gas systems [edit]. Most current gas systems employ some type of piston. The face of the piston is acted upon by gas from the combustion of the propellant from the barrel of the firearm. Early methods such as Browning's 'flapper' prototype, the Bang rifle, and Garand rifle used relatively low-pressure gas from at or near the muzzle.
