This is for you techies looking to get the maximum performance from your VSR or gas blowback Airsoft rifle. This Prometheus inner barrel is 370mm in length and 6.00mm in diameter, that's right - 6.00mm! Truly the tightest of bores!
Prometheus is a well known brand that has been in the Airsoft game for a long time and the quality has always stood at a consistently high level.
Constructed from stainless steel and, the small diameter reduces as much possible air loss and allows for maximum performance and a higher FPS to be reached, although check with your site's FPS limit before bringing your newly upgraded Airsoft rifle to skirmish. Due to the minimal diameter of this barrel, make sure to use high-quality BBs such as the G&G BB range, to avoid potential jamming of BBs.
