Laylax Nine Ball 6.00mm Power Inner Barrel for Umarex G19 & G19X (6.00mm - 85mm)

When every fraction of a second counts in close-quarters sidearm duels, the Laylax Nine Ball 6.00mm Power Inner Barrel (85mm) gives your Umarex/VFC Glock 19 or G19X a decisive competitive edge. Designed by Laylax's dedicated hand-gun division, Nine Ball, this Japanese-crafted inner barrel is purpose-built to extract maximum power and precision from compact gas blowback slide assemblies.

Ultra-Tight 6.00mm Bore Engineering

Standard factory inner barrels typically feature wider internal bores ranging from 6.05mm to 6.08mm, which allows a significant volume of gas to escape around the sides of the BB during discharge. By narrowing the internal diameter down to a precision-ground 6.00mm, this power barrel channels nearly 100% of the expanding propellant directly behind the projectile. This optimized pneumatic compression yields an immediate, noticeable increase in muzzle velocity (FPS) while tightening your shot groupings at medium-to-long engagement ranges.

Precision Japanese Craftsmanship & Crown Finishing

Forged from premium high-density brass with a mirror-polished internal finish, this barrel minimizes surface friction as the BB travels down the 85mm length. The crown at the muzzle end features a micro-beveled cut that stabilizes the air cushion escaping around the BB as it exits the barrel, preventing air turbulence from upsetting backspin trajectory. Additionally, the outer retention notches are precision-machined to drop directly into the stock Umarex G19 hop-up chamber housing without fitting modifications.

Key Features & Technical Benefits:

• Ultra-Tight 6.00mm Inner Diameter: Significantly increases gas compression to boost FPS and shot velocity.

• 85mm Tailored Length: Sized specifically for flush alignment inside standard Umarex/VFC G19 and G19X outer barrels.

• Mirror-Polished Internal Bore: Reduces friction to deliver exceptionally consistent BB backspin and trajectory.

• Precision Muzzle Crown: Stabilizes escaping air pressure at the muzzle to preserve backspin stability.

• Direct Drop-In Japanese Quality: Manufactured to tight tolerances for seamless fitment with stock hop-up assemblies.

Installation & Field Guidance

Due to the ultra-tight 6.00mm internal bore, it is critical to use only high-grade, seamless 5.95mm BBs (such as 0.20g or 0.25g competition-grade rounds) to prevent jams. During installation, thoroughly clean the internal bore using a microfiber patch and alcohol before seating the bucking. Ensure the hop-up bucking alignment ridge sits perfectly square inside the barrel keyway to prevent side-spin flyers on the field.
