The stock MWS hop-up works, but it can drift as you play. First Factory's custom chamber is a drop-in replacement made in Japan by Laylax that locks the hop tensioner more securely, so the hop you dial in stays put. A stable hop setting means more consistent long-range shots, and it's a solid foundation for a bucking and barrel upgrade.

Highlights

  • Drop-in replacement for the stock Tokyo Marui MWS chamber
  • Secures the hop tensioner for a stable setting
  • Built for consistent long-range shooting
  • Zinc diecast construction
  • Made in Japan by First Factory (Laylax)

Fits

Tokyo Marui MWS M4 / AR-15 series gas blowback rifles. Pair it with a PDI 6.01mm tightbore barrel, or browse Hop-Up & Inner Barrels.
