AAP-01 131mm 6.04 Crazy Jet Inner Barrel for GBB Pistol

138mm 6.04 Crazy Jet Inner Barrel for GBB Pistol

The Maple Leaf Crazy Jet series is a line of precision inner barrels engineered specifically to maximize accuracy and consistency in Gas Blowback (GBB) platforms and VSR-10 sniper systems.

Key Technology & Function

• Air Cushion Technology: Features a dual-wall, sleeve-style barrel tip where the inner bore transitions to a wider outer sleeve at the muzzle.

• Turbulence Reduction: High-pressure gas overtakes the BB right before it leaves the muzzle, escaping through the sleeve to create a protective "jet stream" or air cushion around the BB.

• The Result: This design prevents turbulent muzzle gas from destabilizing the BB as it exits, significantly flattening the trajectory and tightening shot groupings.

Specifications & Fitment

• Bore Diameter: Strictly 6.04mm—a specific dimension chosen to optimize air volume balance for the air-cushion effect.

• Material: Precision-machined brass alloy body with a durable stainless steel muzzle sleeve.

• Compatibility: Features standard GBB/VSR cuts, making them a direct drop-in upgrade for Tokyo Marui, WE-Tech, VFC, AAP-01, and KJW gas systems.
