Arcturus RS Steel QPQ Precision 6.02mm / 280mm Airsoft AEG Tightbore Inner Barrel

Arcturus bored this steel barrel to a tight 6.02mm inner diameter, creating a much better air seal around your BBs. By keeping the air pressure locked directly behind the projectile, you get a noticeable bump in muzzle velocity and way less shot dispersion when hitting targets at a distance.

The build quality here is focused entirely on consistency. Because it is machined from high-grade steel, the barrel is incredibly rigid and won't flex or vibrate when you’re leaning on the trigger in semi or full-auto. Arcturus also treated the metal with a specialized QPQ (Quench-Polish-Quench) surface finish. This treatment leaves the inside bore slick, reducing friction and stopping stubborn debris from building up so your feeding stays flawless.

At 280mm long, this barrel is a perfect drop-in fit for shorter platforms like CQB M4s, MK18s, or compact AK variants. It uses standard AEG cuts, meaning you won’t have to fight with compatibility when pairing it with your favorite aftermarket hop-up buckings and chambers. It provides the pressure consistency you need to turn a standard AEG into a highly accurate field rifle. For players looking to get the maximum performance out of their platform, swapping a loose factory barrel for this precision steel piece is one of the most effective upgrades available.
