Angel Custom G2 6.01mm Inner Barrel Series are the pinnacle of quality and performance in the Airsoft Industry. Utilizing advanced machining technology with premium grade materials, these inner barrels stand out in both quality and performance.

After considerable testing and R&D, SUS304 stainless steel was chosen for its qualities that it gives to the application of barrel manufacturing. Despite its higher cost and manufacturing complexity, SUS304 stainless steel provides a such a high degree of hardness, durability, and resilience to ensure the barrel retains its consistency and accuracy even after tens of thousands of rounds. Other qualities of SUS304 stainless steel are that it has natural scuff, corrosion, and weather resistant qualities making it easier to maintain for years of reliability. Each barrel is crafted using precision machinery; a high polish, and precision crowning to provide peak performance.

Compatibility / To Determining the inner barrel length you need:
This barrel is compatible with all Tokyo Marui system AEGs The key to choosing an optimized inner barrel is to prevent it from exposing out of your outer barrel (or flashhider and mock silencer extensions) while maximizing it's length for optimized performance. Please note that the stock barrel length in your gun may not always be optimized for mass production models.

To determine the length you need, measure from where the magazine feed the bb to the tip of your inner barrel, or where you want your inner barrel to end. Subtract ~5mm for hopup unit. Remember, it is perfectly okay to have an inner barrel shorter than your outer barrel, or have the exposed sections hidden in a longer flashhider or mock silencer.

Why Angel Custom?
  • SUS304 stainless steel barrels are simply better than alloy, aluminum, and brass barrels
  • Angel Custom Tight bore barrels are the most affordable steel 6.01mm tight bore barrels
  • Angel Custom's manufacturing capability provides industry leading accuracy and precision

  • Why 6.01mm?
    With the 5.99mm and 5.98mm bbs going extinct, and with present day match grade bbs being 5.88~5.95 for a better center of mass, 6.01mm became the new optimized bore for maximum range, grouping and accuracy.(BB Diameter Deviation Reference: Tokyo Marui / Excel (5.90+). KSC/Evike Japanese Spec. (5.88+). Matrix, WE, AIM Top, Madbull, Elite Force (5.90+).

    6.01mm barrels also provides less air volume in the barrel, resulting less air needed from the cylinder for each projection.

    Inner Barrel FAQ: If you greatly increase the inner barrel of your AEG, you may want to make sure your gearbox Cylinder is adequate. (For example, if you install a 509mm inner barrel on your MP5, you may want to switch the cylinder to a full cylinder so the amount of air inside the cylinder is equivalent to your new barrel.
