The Prometheus EG Barrel [285mm] for Next-Gen CQB-R and MC51 is engineered for exceptional precision, featuring an inner diameter of 6.03mm with a tolerance of just 0.01mm. Crafted from high-strength materials selected without compromise, these barrels forego unnecessary coatings to ensure every element necessary for precise BB trajectory is fulfilled.
 
Inner Barrel: Critical for Accuracy
While real firearms use a single metal tube for the barrel, airsoft guns have an outer barrel for appearance and an inner barrel that accelerates the BBs. The precision of the inner barrel significantly impacts the airsoft gun's accuracy and velocity, making it a crucial component for performance.
 
For Tokyo Marui electric guns, the inner barrel specifications (feed side) are consistent across many models. The EG Barrel Series offers compatibility with these specifications, allowing you to choose from various lengths to match your outer barrel or custom setup.

Note:
After making any custom modifications, always check the joule value and muzzle velocity. Due to recent revisions in gun laws, exceeding the regulation limit of 0.989 joules can result in penalties. Additionally, measurements may vary due to factors such as season, time of day, HOP adjustment, and the specific characteristics of your gun. Ensure you use your airsoft gun within a reasonable joule range.
