One of the most versatile barrels on the market. Choose different fronts for any combination of styles. colors. and lengths. Note: This is just thefront piece of the barrel. Screwing the front into the Freak back will determine how long the total barrel is.(Example: if you have a 16 inch front. that means that the total length of the barrel whenscrewed together. will be 16 inches.) If you do not already have one. you will need to purchase a back and an insert or insert kit to complete the barrel.
