Freak Aluminium Back black /Cocker

Freak System is a modular barrel kit comprised of a back, front and sized inserts to allow maximum paint-to-bore match. The Freak Back is the heart of the system, meticulously machined from high quality aluminum to accept Freak inserts. The beauty of the Freak System is that if you purchase a marker that uses different barrels threads than your current Freak, then you only need to purchase a new Freak Back instead of buying a whole new barrel kit!
