Think upgrades, think Prometheus. This Japanese-made product line by LAYLAX has created a massive name for itself around quality-made precision barrels and quickly became the official upgrade supplier for many brands such as Krytac. Beyond that, Prometheus makes many other upgrade parts for internally upgrading your AEG with high-quality parts that spare no costs for better durability and performance. Expanding beyond internal parts, Prometheus also makes a wide range of colorful accessories which you can use to style your rifle while shaving off weight and improving ergonomics.
