Prometheus 6.03 300mm EG WIDE Tight Bore Inner Barrel 

Introducing Prometheus EG Barrel W; Wide-Expanded HOP window model, based on our EG barrel with the renewed Wide-Expanded HOP window for a variety of HOP nubs and tensioners.

The inner barrel bore width of 6.03mm with a tolerance of 0.01mm, made of stainless steel (SUS) for superior strength necessary to maintain accuracy without the need for coatings. The HOP window adopted in this model is a wide type similar to the Prometheus KRYTAC-compatible EG barrel, making it suitable for setups involving R-HOP and other extended hop tuning techniques. Also compatible with other tuning setups, allowing for a broader range of customization options.
