Maple Leaf Crazy Jet Inner Barrel Chamber Set for Hi-Capa

- Crazy Jet Barrel Maple Leaf is a barrel with a completely new design. Maple Leaf designed a barrel whose end part has a double wall.- When the bullet passes this peculiar collar, gases pushing the bb have the ability to travel with this collar.- These gases form an air tunnel with a ball in the center. This tunnel "paves" the bullet path. It makes it resistant to weather conditions (humidity, side blow), while increasing the accuracy and range.- NOTE: As always, upgrading GBB require necessary skill & technique, consult expertise if needed
