First Factory 6.03mm Inner Barrel for Tokyo Marui MWS / Type 89 GBBR (Length:250mm)

Gas blowback systems such as the Tokyo Marui MWS and Type 89 require incredibly strict tolerance control to deliver consistent FPS and tight groupings during rapid firing. The First Factory LayLax inner barrel perfectly bridges the gap between raw gas pressure and pure downrange accuracy. Measuring exactly 250 mm in length, it tightens the internal bore to a highly precise 6.03 mm, which actively minimizes any air bypass around the BB as it travels. Engineered to drop seamlessly into standard Tokyo Marui gas blowback hop-up chambers, this barrel serves as a highly reliable tolerance upgrade for players who want to optimize their short-barreled CQB setups or custom carbine builds.

Crafted from a high-tolerance plated alloy, this silver inner barrel greatly reduces friction and easily resists long-term oxidation. It is the ideal component for anyone looking to maximize the mechanical efficiency and grouping size of their primary weapon. By installing this upgraded barrel, you guarantee that every bit of gas pressure is utilized effectively, resulting in a much more accurate and consistent platform for your next match.
