Crazy Jet 590mm 6.04 GBB Inner Barrel SP-WII-53 The HAO OTB stock isSRS 420 mm 6. 04 Crazy Jet GBB inner barrel The Maple Leaf Crazy Jet Barrel is a new barrel design. Maple Leaf designed a barrel where the end is wider compared to the rest of the barrel. At the end of the barrel, the air passes around the BB and exits first, and when the BB leaves the barrel, the airflow pulls the BB in what is called a jet stream. This creates less resistance on the BB and will NOT reduce velocity, but instead increase accuracy!
