Precision Accuracy Upgrade for GBB Pistols

The Maple Leaf Crazy Jet 84mm inner barrel is one of the most popular accuracy upgrades for gas blowback airsoft pistols. It swaps out your stock barrel for a precision 6.04mm tightbore built around the well-proven Crazy Jet design, giving you tighter groupings without the fussy cleaning demands of an ultra-tight bore.

How the Crazy Jet Design Works

Unlike a plain tightbore, the Crazy Jet features a widened section near the muzzle that creates an air cushion around the BB as it leaves the barrel. This reduces the air turbulence that normally knocks a BB off line at the moment it exits, so shots leave more consistently and hold a straighter path down range.

Build Quality and Fitment

The barrel uses a brass and steel construction for a hard-wearing, precisely finished bore. The 84mm length is a common gas pistol size suited to G-series and similar compact platforms. Fitting is a straightforward job during a routine strip-down, and our team can handle it for you through our airsoft gun repair and servicing in Kent.

Get the Most From It

Pair the barrel with a fresh hop bucking matched to your BB weight, then feed it consistent, well-polished ammo. Browse our BBs, gas and batteries to complete the setup and unlock the full accuracy potential of your pistol.

Frequently asked questions

What does the Crazy Jet design actually do?

The barrel has a slightly wider section near the muzzle that forms an air cushion around the BB as it exits. This reduces turbulence and helps the BB fly straighter and more consistently than a standard tightbore of the same bore size.

What bore size is this barrel?

It is a 6.04mm inner diameter barrel. That is a balanced tightbore that improves accuracy while remaining more forgiving of BB quality and fouling than an ultra-tight 6.01mm or 6.02mm bore.

Which pistols does the 84mm length suit?

The 84mm length is a common gas blowback pistol fit, typically used in G-series and similar compact GBB pistols. Always compare it against your existing inner barrel before fitting.

Do I need to change my hop rubber too?

For best results, fit a fresh hop bucking matched to your BB weight at the same time. A worn bucking will limit the accuracy gains from a precision barrel.

Is this legal to own and buy?

Yes. An inner barrel is an internal part, not a working airsoft gun, so there is no age or UKARA requirement to purchase it.
