$26.99 USD Save $-26.99 USD

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 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 standard gas blowback (GBB) pistols and similar platforms.

They offer excellent compatibility with:

• Popular Hi-Capa series replicas (e.g., 4.3 models suit the 100mm length; 5.1/Government models suit the 113mm length)
• Many Glock-style GBB pistols (e.g., G17, G19, G34 clones, and variants)
• Other common TM-spec GBB handguns, including models like M&P9, HK45, P226, and similar designs from brands such as WE-Tech, VFC, KJ Works, and AW Custom (as long as they follow Tokyo Marui GBB hop-up chamber standards)

Always verify your replica's stock barrel length and hop-up compatibility for the best fit—minor adjustments or a matching Maple Leaf hop-up chamber/bucking may be needed for non-TM clones. If you're upgrading a Hi-Capa or Glock-style GBB, these are a go-to choice for flatter, more consistent shots!
