Eleven lengths cover everything from pistol to rifle builds.\u003c\/div\u003e\n\u003cp\u003eMost OEM GBB inner barrels run 6.08mm or 6.10mm internal diameter, which leaves room for air to escape around the BB as it travels down the bore. That escaping air is one of the major causes of in-flight instability — turbulent air around a 6mm BB at velocity translates directly into shot-to-shot inconsistency at 30m+. The Maple Leaf Crazy Jet's tighter 6.04mm bore reduces this escape immediately.\u003c\/p\u003e\n\u003cp\u003eWhat makes the Crazy Jet specifically different from other tight-bore upgrades is the air-cushion feature for which it's named. Near the muzzle, the inner bore has cut channels that redirect the high-pressure air behind the BB into a controlled flow pattern, creating a secondary 'air barrel' around the BB as it exits. Instead of random muzzle turbulence destabilising the BB at the moment it leaves the barrel, the air pattern stabilises it. The result is measurably tighter groupings at 30–50m, particularly noticeable on heavier BBs (0.30g+) and on builds where the barrel is the consistency bottleneck.\u003c\/p\u003e\n\u003cp\u003eThe Crazy Jet range covers eleven lengths. 113mm is the standard pistol length — fits most full-size GBB pistols including TM Hi-Capa and 1911 platforms. 150mm and 180mm cover longer pistols, SMG conversions and short-barrel rifles. 310mm fits standard M4-class GBBRs. 410mm is the long-barrel length for DMR-style GBBR builds and 16\" rifle profiles.\u003c\/p\u003e\n\u003cp\u003eCompatible with standard GBB hop-up chambers. Brass-and-alloy construction with Maple Leaf's consistent QC. Best paired with a Maple Leaf hop bucking for full system optimisation, though the barrel works fine with most aftermarket buckings.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 16px; color: #1b3a6b; margin: 18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; font-size: 13px; margin: 0 0 18px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background: #1B3A6B; color: #fff;\"\u003e\n\u003cth style=\"padding: 7px 12px; text-align: left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding: 7px 12px; text-align: left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background: #f5f5f5;\"\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003eBore diameter\u003c\/td\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003e6.04mm precision\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003eConstruction\u003c\/td\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003eBrass and alloy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background: #f5f5f5;\"\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003eAir-cushion design\u003c\/td\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003eYes — muzzle-end channels create stabilising airflow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003eCompatible platform\u003c\/td\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003eStandard GBB \/ GBBR hop-up chambers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background: #f5f5f5;\"\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003eLengths available\u003c\/td\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003e97mm, 100mm, 113mm, 117mm, 150mm, 180mm, 200mm, 220mm, 275mm, 310mm, 410mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003ePairs best with\u003c\/td\u003e\n\u003ctd style=\"padding: 7px 12px; border: 1px solid #eee;\"\u003eMaple Leaf hop-up bucking (60° or 70°)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background: #1B3A6B; color: #fff; padding: 12px 16px; border-radius: 6px; margin: 18px 0 0; font-size: 13px;\"\u003e\n\u003cstrong style=\"color: #fff;\"\u003e💡 Titan Forge Airsoft tip:\u003c\/strong\u003e If you've already upgraded the hop bucking and are still seeing inconsistent groups, the barrel is usually the next limiting factor — this is the easiest upgrade to do that, with a noticeable result.
