The Poseidon 6.05mm Air Cushion inner barrel is designed for GBB pistols where barrel space is limited. At 113mm it fits compact platforms like the Hi-Capa, M1911, and similar slide assemblies. The 6.05mm bore is tighter than standard 6.08mm or 6.09mm barrels, which can improve air seal when paired with quality BBs. The nickel-plated copper construction resists corrosion.
Compatibility. Fits Tokyo Marui and WE Tech GBB series pistols. Check your pistol's inner barrel mounting style before ordering—some platforms use a threaded fit, others press-in. This is a direct replacement for stock barrels, not an upgrade for AEGs.
Includes only the inner barrel. Installation requires basic gunsmithing tools and familiarity with GBB pistol disassembly. As with any barrel upgrade, test your pistol's performance after installation and adjust your hop-up as needed.
