Prometheus Airsoft 6.03mm EG Precision Barrel 120mm G&G Firehawk

Prometheus 6.03 EG Precision Steel Inner Barrel 120mm – Firehawk

If you’re upgrading a compact AEG and want tighter shot grouping and better consistency without going overboard on ultra-tight bore setups, the Prometheus 6.03 EG Precision Barrel 120mm from Bullseye Country Sport is one of the best inner barrel upgrades you can fit. Designed specifically for the G&G Firehawk platform and G&G AEGs, this barrel combines proper Japanese machining quality with excellent air efficiency and accuracy improvements.

Prometheus barrels have a serious reputation in the airsoft world for a reason. Manufactured in Japan using high-grade SUS stainless steel, this barrel features an ultra-consistent 6.03 mm inner bore with an impressive ±0.01 mm tolerance, helping improve BB stability, air seal consistency and overall shot accuracy.

Unlike some ultra-tight barrels that can become picky with ammo quality, the 6.03 bore size gives a brilliant balance between performance, reliability and ease of maintenance. It’s particularly popular among players wanting improved accuracy while still maintaining dependable feeding during skirmishes.

Prometheus also designed this specific 120 mm version around the G&G Firehawk and similar compact AEG platforms, carefully matching the barrel dimensions and finish to optimise performance in shorter builds. At Bullseye Country Sport, we reckon Prometheus barrels are still some of the best-performing AEG inner barrels on the market if you want genuine performance gains without gimmicks.
