The barrel can be screwed into the rifle block using the threading at the back, with the liner placed inside the barrel housing. A ½” UNF barrel thread allows for the mounting of a muzzle brake or moderator. The Bull barrel kit is compatible with all existing FX Dynamic Blocks and Dynamic MKII Blocks. This makes this barrel kit also suitable for older versions of the FX Panthera, FX Dynamic or FX King.
