Prometheus Inner Barrel Prometheus EG 6.03 wide — 300

With this Prometheus EG 6.03 Wide inner barrel, you’ll have even more options for fine-tuning and customizing your airsoft replica. The inner barrel is made of stainless steel, which expands less with heat than brass and aluminum, the materials used for most inner barrels. A hot barrel will have little or no effect on accuracy. The 6.03 mm inner diameter ensures that 6 mm BBs fit perfectly through the barrel. There’s a larger opening at the front end of the barrel, which is deeper and wider than on other inner barrels. This gives you more options for different types of hop-up buckings, allowing you to customize your airsoft replica even further. The Prometheus EG 6.03 Wide inner barrel is available in different lengths.

Please note: This inner barrel is not compatible with the MP5 A5, MP5 SD6, or M14 series.
