Arguably the heart of any airsoft gun, the barrel determines various performance factors such as speed (FPS), accuracy and precision (consistency). Real steel guns have a single metal barrel, while airsoft gun barrels have two parts, an inner and an outer barrel. The outer barrel reproduces the look of a real steel barrel, while the inner barrel is the actual barrel that fires the BB.

The EG Barrel series is based on Tokyo Marui specification barrels. EG barrels fit a wide variety of guns and outer barrels, allowing you to choose from a wide range of barrel lengths that best suit your own custom build!
