  • 6.00mm Precision barrel
  • Stainless steel construction
  • For Hi-Capa pistols

If you want to improve your 5.1 Hi-Capa's accuracy, range and consistency, a barrel upgrade is a great start! The Laylax Nine Ball 6.00mm Steel Tightbore Inner Barrel is a huge improvement over stock 6.03mm brass tightbore barrels, and its stainless steel construction makes it far more rigid and less prone to bends than other brass and aluminium barrels.

This barrel is cut for Tokyo Marui Hi-Capas and clones and should fit most of them, provided they are 5.1 editions. This barrel has an inner diameter of 6mm, which means that you will have to use high-quality BB ammo to ensure no blockages. However, when used with a high-quality BB, you will have the most consistent performance available, as there will be next to no air loss when shooting.

  • 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.

  • 370mm length
  • 6.00mm diameter +/-10%
  • Stainless steel build

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.
