Prometheus ASH Barrel 110mm Tokyo Marui MP5K

Standard 110mm length inner barrel (for MP5K), the ASH series are metal inner barrels with a durable grey finish that serves to reduce friction (reducing air turbulence), resist environmental damage and leave it with a subdued "gun metal" tone.

6.05mm inner diameter is exactly precise to ensure reliability yet generous enough in size to accommodate a wider variety of ammunition brands then the tighter tolerance of 6.01mm barrels. Prometheus offers supreme quality products because when it comes to precision performance, its whats inside that counts.
