The Archwick Tightbore Barrel – GBB – 113mm is a precision inner barrel for gas blowback airsoft builds where accuracy and consistency matter. At 113mm in length with a 6.03mm inner diameter, it is aimed at players who want a more refined shot path from a compact GBB platform without adding unnecessary complexity.
Made from brass and precision honed, this barrel is finished with a polished internal surface to help BBs travel more smoothly through the bore. In practical use, that can translate into a more predictable feel shot to shot, which is especially useful when you need quick follow-up shots and better confidence at typical skirmish distances.
The nickel coating adds a further layer of protection against wear while also helping reduce friction inside the barrel. That makes it a sensible choice for regular players maintaining a performance-focused sidearm or tightening up a compact gas blowback setup.
Before fitting, always confirm compatibility with your specific GBB model and barrel length requirements. For a well-matched build, it also makes sense to look at suitable GBB hop rubbers and airsoft cleaning accessories.
