The Maple Leaf Crazy Jet Barrel System is a super cool inner barrel design for airsoft gun upgrades. A 6.02mm precision Maple Leaf i nner 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. Several types of barrel fits: GBB cut - works on AEG and gas gun hop up chambers (AEG must use AEG bucking) VSR cut - works on VSR rifles and VSR buckings only KWA cut - works on KWA MP7 only GBB is the cut for most of the barrels on the drop-down menu. The GBB barrels work on both AEGs and Gas Blowback pistols/rifles hopup chamber systems. AEGs must use a Maple Leaf AEG style bucking to fit properly (non-Maple Leaf AEG buckings may not work). AEG Macaron, MR Hop, Super Macaron AEG all work perfectly with these barrels and AEG chambers. 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 Hop Up bucking from Maple Leaf. Gas guns can use the Maple Leaf or standard GBB buckings. We highly recommend Maple Leaf buckings for this system. These are a drop-in fit for GBB Gas blowback guns from: WE, Tokyo Marui, VFC, and AW Custom, KJW guns, etc. The 100mm fits HiCapa 4.3; 113mm fits HiCapa 5.1 - Tokyo Marui or WE brand gas pistols. Drop-in fit. 86mm is for Glock 19 / G19x. The VSR barrels are specifically designed for the Tokyo Marui VSR-10 rifles (cut for VSR/GBB buckings only). The 300mm, 430mm and other VSR lengths are also cut for VSR buckings. The VSR specific cut is required for stock VSR-10 hop up chambers, but not for the Action Army Hop up Chamber . For the Action Army Chamber, you are able to use any inner barrel as long as its designed for GBB/VSR buckings(Non KWA/KSC) and is
