Laylax Steel Inner Barrel for GBB (6.00mm - 133mm)
Boost muzzle velocity and achieve pinpoint accuracy in compact builds with the LayLax Steel Inner Barrel for GBB(6.00mm - 133mm). Precision-engineered in Japan, this ultra-tightbore 6.00mm inner barrel maximizes air retention behind the BB, significantly increasing FPS without requiring a heavier gearbox spring. Crafted from durable stainless steel, it features an ultra-smooth internal bore polish that minimizes friction for exceptionally stable trajectories. Measuring 133mm in length, it serves as an ideal performance upgrade for ultra-compact AEGs, SMGs, and shortened carbine platforms. Elevate your compact replica's efficiency with premium LayLax engineering.
When tuning compact AEG platforms, maximizing compression and barrel efficiency is key to maintaining high velocity and tight shot groupings. The LayLax Steel Inner Barrel for GBB(6.00mm - 133mm) delivers exceptional Japanese precision engineering designed to squeeze maximum performance out of short-barreled airsoft builds.
High-Efficiency 6.00mm Tightbore Diameter
Featuring an ultra-tight 6.00mm internal diameter, this inner barrel creates a tight air seal around the BB as it travels through the tube. By drastically reducing air leakage around the projectile, more energy from the cylinder compression is transferred directly behind the BB. This results in a noticeable increase in FPS (feet per second) while maintaining your current gearbox setup, allowing you to maximize output on builds where cylinder volume is restricted by shorter barrel lengths.
Premium Stainless Steel Construction & Polish
Manufactured from high-grade stainless steel, this LayLax inner barrel is built to resist flexing, vibration, and internal corrosion over hundreds of thousands of rounds. The interior wall is treated with a mirror-finish polish, reducing surface friction as the BB travels down the bore. This ultra-smooth path stabilizes spin imparted by the hop-up bucking, delivering flatter trajectories, reduced flyers, and superior grouping consistency at range.
Precision Machined Hop-Up Window & Universal GBB Spec
The 133mm length is tailored specifically for compact GBB configurations, such as submachine guns, shorty M4/AR-15 variants, and custom CQB setups. It features a precision-cut hop-up window and barrel retention grooves that ensure seamless compatibility with standard GBB hop-up buckings and chambers. For optimal performance and to prevent jams, using high-quality, high-precision polished BBs (such as 5.95mm ± 0.01mm tolerance) is highly recommended with this 6.00mm tightbore barrel.
