- 6.03mm Tightbore inner barrel
- Stainless steel construction
- For TM-compatible pistols
If you are after a bit more accuracy from your GBB pistol, a tightbore barrel is the easiest and most effective solution! Introducing the 6.03mm Tightbore Inner Barrel from Nine Ball, one of the best inner barrels you can treat yourself to. The Inner Barrel features standard inner barrel cuts, meaning the barrel is compatible with TM-based GBB pistols with the VSR style bucking (WE, Umarex G series etc.). Due to its length, we recommend this for GBB pistols, specifically HI-CAPA 5.1 and 4.3.
The inner barrel is constructed from stainless steel, with a highly polished internal surface for minimal friction and a deep and smooth crown to ensure your BB leaves the barrel smoothly and consistently. This barrel is cut for either VSR/GBB style HOP buckings.

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.
