Arcturus 6.02mm Precision QPQ Steel Tight Bore Inner Barrel – 345mm for Tokyo Marui Spec AEGs

When it comes to upgrading your airsoft rifle, precision matters. The Arcturus 6.02mm Precision QPQ Steel Tight Bore Inner Barrel is designed for serious players who demand tighter groupings, improved consistency, and maximum durability. Built to exacting standards and finished with advanced QPQ treatment, this 345mm barrel delivers professional-grade performance that can transform the accuracy of your Tokyo Marui-spec AEG.

Engineered for Accuracy

A tight bore barrel is one of the most effective internal upgrades you can make to your airsoft gun, and Arcturus has taken this to the next level. With an inner diameter of just 6.02mm, this barrel minimizes air loss, creating a better air seal between the BB and barrel walls. This results in a more consistent muzzle velocity, improved range, and tighter shot groupings. Whether you’re engaging targets at medium distance or need that first-shot hit in competition, this barrel gives you the edge.

Durability That Lasts

The Arcturus 6.02mm Tight Bore Barrel is made from ultra-durable steel, ensuring exceptional strength and resistance to bending or warping. Unlike softer materials, this hardened steel can withstand the wear and tear of heavy use, even in high-rate-of-fire setups. It’s built to be a long-term investment in your AEG’s performance.

Advanced QPQ Finish

The QPQ (Quench Polish Quench) finishing process is what sets this barrel apart from ordinary options. This advanced surface treatment hardens the steel while producing a smooth, corrosion-resistant finish that reduces friction as BBs travel down the barrel. The result? A cleaner shot, less wear on BBs, and consistent accuracy even after extended play.

Optimized Length – 345mm

At 345mm, this barrel is ideal for mid-length AEG builds. It offers a perfect balance between maneuverability and accuracy, making it suitable for both field and CQB rifles that benefit from extended inner barrels. It’s long enough to provide a stability boost for your shots but not so long that it compromises handling in tight spaces.

Easy Compatibility

This barrel is designed to fit Tokyo Marui-spec AEGs and other compatible platforms, making it a versatile upgrade option. Installation is straightforward for players with basic teching experience, and it pairs perfectly with high-quality hop-up units and buckings for even greater performance gains.
