■PROMETHEUS EG Barrel Series

●Inner bore width of φ6.03mm with a ±0.01mm tolerance!
●Solid BB stability and accuracy, made with enhanced stainless steel (SUS) material!

Inner barrel bore width of 6.03mm with a tolerance of ±0.01mm, made of stainless steel for superior strength necessary to maintain accuracy without the need for coatings. 

■The barrel is arguably the heart of any airsoft gun and determines various performance factors such as velocity (FPS), accuracy, and precision (consistency). Real steel guns have a single metal barrel while airsoft gun barrels come in two pieces, an inner and outer barrel. The outer barrel reproduces the appearance of a real steel barrel, while the inner barrel is the actual barrel which fires the BB.

■The EG Barrel Series is based off of the Tokyo Marui specification barrels. EG Barrels fit a variety of guns and outer barrels, so you can choose from a wide selection of barrel lengths that best suits your own custom build!


■Length: 141 mm matched length for MP5 PDW
