PRK is short for Pack Rifle Kit. The PRK converts your Keystone Arms, Crickett or Chipmunk youth rifle into one of the Worlds lightest, take down rifles(We designed the lightest at 15.5oz as well). The PRK replaces the barrel and stock of your Crickett or Chipmunk rifle with light weight alternatives, shaving 1 pound 10 ounces out of the OEM version. The barrel is constructed of a carbon fiber outer, with titanium and aluminum components joining the carbon fiber outer to the Cro-Moly steel, button rifled barrel liner. The carbon fiber tube stock is simple and functional, it is made of carbon fiber and aluminum tube. The stock corrects the angle and length of pull to make it comfortable for adults to use. The butt stock removes to allow storage in the stock tube. While the stock comes on and off with a few turns of a thumb screw.

Installation involves removing the roll pin and set screw that hold the barrel on, and replacing them with the carbon barrel, and set screw we provide. The roll pin is no longer used. The updated version of the barrel drops in with no need to set the head space.   This is just a kit, not a complete rifle.    The loading ramp on newer Crickett rifles must be removed to install the kit.
