Category: Tags: , ,


The Maple Leaf Crazy Jet Barrel System is a super cool inner barrel design for airsoft gun upgrades.  A 6.04mm precision brass made inner barrel with a finely tuned end piece that is slightly larger to create an “air cushion” surrounding the BB as it exits the barrel.  This system reduces air turbulence as the BB leaves the barrel, greatly increasing its accuracy and intended trajectory.  The barrel end is 6.12mm inner diameter to create the air insulation.

The Crazy Jet will not increase speed or distance, but will increase its accuracy.  Works great on handguns and longer guns alike. These barrels will also work with AEGs when coupled with the Hot Shot hop up rubber bucking from Maple Leaf. Gas guns can use the Hot Shot or standard GBB buckings. We recommend Maple Leaf buckings for this system.

These are a drop-in fit for GBB Gas blowback guns from:  WE, Tokyo Marui, VFC, and KJW guns.

The 100mm fits HiCapa 4.3; 113mm fits HiCapa 5.1 – Tokyo Marui or WE brand gas pistols.  Drop-in fit.

    Only place in nz that sells this particular length. My tm mk23 now shoots more accurately and being a 138mm barrel keeps the fps to side arm specs.
