The Freak Insert is at the literal core of the Freak barrel system. Paintballs can change size from thousands of variables; temperature, humidity, elevation, storage conditions and manufacturers to name a few. The interchangeable bore system allows players to adapt to whatever paintball throws at them.
The boremaster kit gets you 8 of the most common bore sizes and a rugged case to carry them in, the case also holds two freak tips and a back.
The aircraft grade aluminum Freak insert is the perfect balance of weight and durability. The honed internal finish is protected by top quality anodization. The 8 inserts in an aluminum boremaster are: .679 / .682 / .684 / .687 / .689 / .691 / .693 / .695
