Angel Custom G2 SUS304 Stainless Steel 6.01mm Inner Barrel for Airsoft GBB Pistols – Precision, Durability, and Unmatched Accuracy

Upgrade your Airsoft gas blowback pistol with the Angel Custom G2 SUS304 Stainless Steel Precision 6.01mm Inner Barrel, engineered to maximize accuracy, range, and performance. Designed for Tokyo Marui, WE-Tech, and other compatible 6” Hi-CAPA and 1911 series pistols, this high-end tightbore barrel is the ultimate solution for players seeking pinpoint grouping and enhanced FPS performance.

Crafted from premium SUS304 stainless steel, Angel Custom has created an inner barrel series that is unmatched in strength, durability, and corrosion resistance. Unlike aluminum, brass, or alloy barrels, SUS304 steel provides exceptional hardness, ensuring your barrel retains its precision even after tens of thousands of rounds. Its natural resistance to rust, stains, and wear makes maintenance effortless, guaranteeing consistent performance in all weather conditions.

The 6.01mm bore diameter is optimized for modern match-grade BBs ranging from 5.88mm to 5.95mm, providing a perfect balance between air efficiency and projectile stability. This tightbore design minimizes air volume loss during firing, resulting in faster FPS and improved consistency shot after shot. Angel Custom has carefully engineered this barrel to reduce vibration during rapid fire, offering players enhanced control and accuracy for both casual skirmishes and competitive play.

Each barrel features CNC-milled channels for secure attachment to your hop-up unit and an angled window to reduce wear on your bucking. Precision CNC milling, surface polishing, and tapered crowning ensure superior barrel alignment, consistent airflow, and minimal friction for your BBs. Individually crowned edges improve performance and accuracy by providing a true exit path for the projectile, maximizing your effective range.

Players will immediately notice power gains of 20–50 FPS, depending on barrel length, along with improved grouping and distance. The high polish finish and precision craftsmanship ensure smooth BB travel, giving your shots remarkable stability. Whether you are participating in field games, skirmishes, or competition, the Angel Custom G2 barrel enhances your pistol’s performance to its full potential.

Compatibility is key for any upgrade. This “Extended Hi-CAPA” barrel is specifically designed for:

• Tokyo Marui Hi-CAPA 5.1 / 1911 series

• WE-Tech 6” Hi-CAPA

• 7” Dragon

• Other compatible Airsoft GBB pistols

To select the proper barrel length, measure from your magazine feed point to the tip of your inner barrel and subtract approximately 5mm to account for the hop-up unit. Note that it is acceptable for the inner barrel to be slightly shorter than the outer barrel, especially if the exposed section is hidden by a flash hider or mock silencer.
