Lambda “One” Precision Barrel – 6.01mm Tight Bore Upgrade for Tokyo Marui GBB Pistols

Engineered for competitive airsoft players seeking unmatched accuracy, the Lambda “One” stainless steel inner barrel delivers tournament-grade performance. Crafted in Osaka using cold-forged SUS304 steel, this precision-machined barrel features an ultra-tight 6.01mm bore with ±1 micron tolerance for consistent shot grouping at extended ranges.

Performance-Driven Features:
– Laser-Precise Boring: The mirror-polished 6.01mm diameter minimizes BB wobble while maintaining optimal air seal
– Durability Meets Precision: SUS304 stainless steel construction resists wear while the hand-finished crown reduces turbulence
– Drop-In Compatibility: Designed specifically for Tokyo Marui G-series GBB pistols (97mm/102mm/118mm length options available)
– Tournament-Ready Consistency: Cold forging process ensures dimensional stability across temperature variations

Ideal for Hi-Capa and 1911 platform upgrades, this Japanese-made barrel helps eliminate vertical stringing and improves gas efficiency. The high-polish interior reduces friction for smoother BB travel compared to standard brass barrels, giving you tighter groupings during speedsoft matches or precision shooting drills.

Whether you’re upgrading your competition pistol or building a custom airsoft sidearm, the Lambda “One” series represents the pinnacle of barrel technology – where Japanese craftsmanship meets measurable performance gains on the field.
