The T238 Piston Rack Basic Edition is an ultra–budget-friendly upgrade designed for players who want a stronger, more reliable piston without increasing build costs. Priced at just $8, it offers a substantial durability improvement over standard OEM pistons while maintaining compatibility with all Tokyo Marui–standard V2/V3 gearboxes and their derivatives—including M4, AK, MP5, G36, P90, AUG, VECTOR, and similar models.
Featuring stainless steel teeth paired with a PA66-33G reinforced polymer body, this piston rack provides smoother engagement and increased longevity for day-to-day use. The standard 5 mm piston head interface ensures compatibility with most aftermarket piston heads. A practical, cost-effective choice for players upgrading on a budget or refreshing older builds.
