Inner Barrel Prometheus EG 6.03 GBB Tokyo Marui M4A1 MWS 370 mm
Direct leverbaar
Looking for more range and a more stable shot from your Tokyo Marui M4A1 MWS? Then this Prometheus EG 6.03 GBB inner barrel of 370 mm is an upgrade worth considering.
Where the original Tokyo Marui M4A1 MWS inner barrel measures 250 mm, this version comes in significantly longer at 370 mm. That extra length translates into increased power for your replica.
Stainless steel forms the material of this Prometheus EG 6.03 GBB 370 mm barrel. A deliberate choice, as gas fumes corrode a regular inner barrel faster; this type resists that wear better. For GBB shooters looking to upgrade their M4, a logical option.
