Laylax Nine Ball 6.03mm Tightbore Inner Barrel for EMG TTI JW3 2011 Combat Master (6.03mm - 120mm)

The EMG TTI JW3 2011 Combat Master is a iconic competition-style sidearm, but achieving match-winning accuracy requires internal consistency that lives up to its tactical aesthetic. The Laylax Nine Ball 6.03mm Tightbore Inner Barrel (120mm) bridges this gap, bringing world-class Japanese engineering directly to your 2011 GBB platform.

High-Grade Stainless Steel & 6.03mm Precision Bore

Standard factory inner barrels often utilize wider internal tolerances that allow pressurized gas to spill past the projectile upon discharge. CNC-machined from cold-forged stainless steel, this Nine Ball barrel features a tight 6.03mm internal diameter with a strict ±0.01mm tolerance. This creates a superior pneumatic seal behind standard 5.95mm BBs, converting expanding propellant gas into immediate muzzle velocity gains (FPS) without requiring high-flow valves or heavier recoil springs.

Lapped Interior Finish & Precision Target Crown

The interior wall of the barrel undergoes a meticulous hand-polishing and lapping process to achieve a mirror-smooth finish. This minimizes mechanical friction as the BB accelerates down the 120mm length, preserving backspin energy generated by your hop-up bucking. At the muzzle tip, a precision-cut target crown evenly releases escaping gas behind the BB, ensuring a clean transition into free flight without turbulent air disrupting long-range stability.

Key Features & Technical Benefits:

• 6.03mm Precision Tightbore Diameter: Maximizes gas seal efficiency for higher FPS and consistent velocity.

• SUS Stainless Steel Construction: Provides rigid structural stability that resists bending, wear, and corrosion.

• 120mm Custom Tailored Length: Direct factory drop-in fitment for the EMG TTI JW3 2011 Combat Master GBB pistol.

• Mirror-Polished Internal Bore: Minimizes friction to ensure consistent hop-up backspin and flight trajectory.

• Made in Japan Quality: Precision-machined to match TM/WE-spec Hi-Capa hop-up chambers effortlessly.

Installation & Field Guidance

Before seating the barrel into your Combat Master's hop-up chamber, draw a clean microfiber patch lightly dampened with isopropyl alcohol through the bore to clear any protective factory packaging film. Pair this barrel with a high-performance 60° gas hop-up bucking for optimal trajectory control. To prevent jams within the precision 6.03mm bore, strictly use high-grade, seamless 5.95mm competition BBs during skirmishes.
