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.

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 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.

※Be sure to clean the barrel's interior before use.
※Do not re-use BBs or use BBs have fallen on the ground. The tight inner diameter of the barrel may cause blockage with deformed or unclean BBs such as dust or dirt.
