Enhance your GBB Pistol Accuracy Today!

Ready to elevate your GBB pistols performance? Well be sure to pickup a barrel upgrade!

This premium tight-bore barrel features Maple Leaf's signature Crazy Jet design: a ported muzzle that creates an air cushion around the BB as it exits, reducing turbulence and stabilizing flight for flatter trajectories and tighter groups — especially at range.

• 6.02mm precision bore — Improved consistency, gas efficiency, and velocity over stock barrels.
• Brass Alloy construction — Durable, smooth, and corrosion-resistant.
• Wide compatibility — Great for GBB pistols/SMGs (verify length/platform fit).

Trusted by players for superior mid-to-long-range performance. Pair it with our bucking upgrades for maximum results!

Compatibility:

These Maple Leaf Crazy Jet 6.02 tight-bore barrels (available in 100mm and 113mm lengths) are designed as drop-in upgrades for most Tokyo Marui-spec gas blowback (GBB) pistols and similar platforms.

• 100mm Length: Ideal for Hi-Capa 4.3 models, Glock 17/18C, and similar mid-size GBB pistols.
• 113mm Length: Ideal for Hi-Capa 5.1, 1911 Government models, Glock 34, and similar long-slide pistols.
  

Always verify your replica's exact stock barrel length and hop-up compatibility before purchasing. While these are a go-to choice for flatter, more consistent shots in standard Hi-Capa and Glock-style GBBs, certain pistols may require minor adjustments / modifications or a matching Maple Leaf hop-up chamber and bucking for the absolute best air seal and fit.
