Description
Laylax Nine Ball High Bullet Valve NEO RR for Tokyo Marui SOCOM Mk23
This Nine Ball High Bullet Valve NEO RR is an upgrade valve for the Tokyo Marui SOCOM Mk23 gas pistol. The Mk23 is a large, accurate pistol often used as a quiet sidearm with a long silencer, and the valve is one of the parts that controls how efficiently gas is delivered behind each BB.
LayLax is a long-established Japanese maker of airsoft parts, with sub-brands including Prometheus for internal upgrades, Nine Ball for gas pistol parts and First Factory for external and replacement parts.
What it does
As its name suggests, the High Bullet range is aimed at raising BB velocity by improving how gas is used for each shot. Because a valve upgrade can change your pistol’s output, always have it chronographed after fitting and before taking it to a game, and make sure it stays within your site’s limits.
A fresh valve can also restore performance on a well-used pistol where the original has become tired.
Fitting
Valve work needs care, as parts are small and spring-loaded. Work on a clean surface, take photos as you strip the pistol and keep parts in order. Fit the valve as the instructions describe, then test with gas and no BBs before firing at a safe backstop.

Compatibility
Made for the Tokyo Marui SOCOM Mk23. Mk23 replicas from other makers may use different internals. Spare parts are often specific to one manufacturer, and sometimes to one production version, so please compare this part with the one you are replacing, or contact us with your replica’s make and model, before ordering.
Care and maintenance
Put a drop of silicone oil on magazine seals every few fills and store magazines with a little gas in them. Keep the slide rails lightly lubricated, clean the inner barrel with a rod and dry patch, and use good quality seamless BBs.
Gas pistol internals are made to close tolerances. If you are not confident working on your replica, have the part fitted by an experienced technician.
Who is it for?
It is for Tokyo Marui SOCOM Mk23 owners who want to get more efficiency and consistency from their pistol, or freshen up a well-used one.
Please note: Gas, BBs and tools are not included. Always have your pistol chronographed after fitting and before play.
