The Maple Leaf Crazy Jet 6.04 mm - 84 mm Precision Inner Barrel is designed for GBB (Gas Blowback) airsoft pistols compatible with the Tokyo Marui standard. Featuring a 6.04 mm inner diameter and the patented Crazy Jet technology, it enhances BB stability as it exits the barrel, delivering improved accuracy and greater shot consistency compared to standard inner barrels.
The Crazy Jet design incorporates a specially engineered muzzle section that directs airflow around the BB as it leaves the barrel, reducing turbulence and helping to maintain a more stable flight path. Manufactured from high-quality materials, this barrel is a popular upgrade for GBB airsoft pistols.
