Maple Leaf 6.04mm "Crazy Jet" Inner Barrel for Gas Blowback Airsoft Guns (410mm)
If you're looking to maximise the performance of your gas blowback airsoft rifle, the Maple Leaf 6.04mm Crazy Jet Inner Barrel (410mm) is a proven upgrade designed to improve accuracy, consistency, and effective range. Widely regarded as one of the most innovative inner barrel designs available, the Crazy Jet series has become a favourite among airsoft players seeking enhanced performance without complex modifications.
What makes the Crazy Jet different from a conventional airsoft inner barrel is its unique muzzle design. Near the end of the barrel, a specially engineered expansion section allows a controlled amount of gas to pass around the BB as it exits. This creates a cushion of moving air ahead of the projectile, helping to stabilise its flight path and reduce turbulence. The result is a smoother trajectory with the potential for tighter groupings and improved long-range performance.
The precision 6.04mm tightbore diameter offers an ideal balance between air efficiency and BB stability, making it suitable for players who want improved shot consistency without sacrificing reliability. At 410mm in length, this barrel is particularly well suited to full-length gas blowback airsoft rifles, DMR-style builds, and custom GBB platforms where maximum accuracy and range are priorities.
Manufactured by Maple Leaf, a trusted name in airsoft upgrade components, the Crazy Jet barrel is precision-machined to high tolerances for dependable performance in demanding skirmish environments. Whether you're upgrading a GBB M4, a designated marksman rifle, or a custom long-range airsoft build, this inner barrel is an excellent choice for extracting the most from your setup.
Please note that Maple Leaf is currently transitioning these barrels to a silver finish. Depending on stock availability, customers may receive either the previous finish or the newer silver version. This is purely a cosmetic change and does not affect performance, quality, or compatibility.
