We contracted out the production to a CNC factory that specialises in high-end metalwork, this is very apparent from looking at the outside of the barrel. For the inner surface they suggested a finely uniformed surface that distributes the air and helps to create a cushion surrounding the BB on all sides helping to control the spin.
- Enlarged hop window (6mm long and 4mm wide), designed for hop rubbers with larger contact patches, (will also work with smaller patches)
- End stabalising groove
- Deep crowns
- 30 day no-quibble returns policy.
