Angel Custom G2 SUS304 6.01mm Precision Airsoft Sniper Rifle Inner Barrel – 500mm APS2

Elevate your airsoft sniper rifle’s performance with the Angel Custom G2 SUS304 Stainless Steel 6.01mm Inner Barrel. Engineered for serious marksmen and competitive players, this inner barrel is designed to maximize accuracy, range, and consistency for APS2, Type9, UTG MB-01, and other compatible series sniper rifles. Angel Custom combines advanced materials with precision CNC machining to produce a barrel that outperforms standard options in both durability and performance.

Precision Engineering for Superior Accuracy

Every G2 6.01mm inner barrel is crafted from 100% SUS304 stainless steel, a material chosen for its exceptional hardness, corrosion resistance, and weatherproof qualities. Unlike aluminum, alloy, or brass barrels, SUS304 stainless steel retains its shape and performance even after tens of thousands of rounds, ensuring long-term consistency. The barrel undergoes precision surface polishing and CNC-milled crowning, giving each unit a perfect tapered edge for improved grouping, smoother shots, and reliable long-range performance.

The 6.01mm bore diameter is optimized for today’s match-grade BBs, which range from 5.88mm to 5.95mm. This slightly larger bore reduces air volume per shot, improving muzzle velocity efficiency and allowing more consistent propulsion with each BB. The result is tighter groupings, increased accuracy, and extended effective range.

Performance Benefits

• Increased FPS: Up to 20–50 FPS improvement, depending on rifle setup and barrel length.

• Enhanced Range: Optimized for both maximum and effective shooting distances.

• Vibration Reduction: Minimizes barrel vibration during rapid fire, ensuring consistent shot placement.

• Secure Fit: Milled channels and angled hopup window reduce wear on hopup bucking and maintain proper alignment.

With its 500mm length, this barrel is ideal for APS2 sniper systems and can also fit Type9, UTG MB-01, and other APS-compatible rifles. Its precision machining ensures seamless installation and compatibility, whether you’re running a full-length barrel or using a mock suppressor.

Why Choose Angel Custom

Angel Custom G2 barrels are renowned for industry-leading precision and affordability. By using SUS304 stainless steel, Angel Custom provides a barrel that surpasses standard alloy or brass alternatives in both durability and performance. The tight 6.01mm bore accommodates modern match-grade BBs, producing tighter groupings and more reliable long-range shots. Each barrel is individually crowned to guarantee consistency shot after shot, making it an ideal upgrade for serious airsoft players looking to dominate the field.

Installation Notes

To determine the correct barrel length for your rifle, measure from the magazine feed point to the tip of the inner barrel, subtracting ~5mm for the hopup unit. It is acceptable to have a slightly shorter inner barrel than your outer barrel, as exposed sections can be concealed under flash hiders or mock suppressors.
