For the competitive shooter who refuses to leave anything to chance, every component of their pistol must work in absolute harmony. The JDG Tokyo Marui Hi Capa CompMag Magazine Extension Pad 170mm Type Performance Version - Black is not simply an accessory; it is a meticulously engineered performance tool designed specifically for IPSC athletes who demand precision, stability, and consistency with every shot. Crafted through extensive consultation and real-world testing with a team of dedicated competitive shooters, this magazine extension has been refined to meet the unforgiving demands of high-intensity match conditions. Every decision?from material selection to final assembly?reflects a singular focus on delivering unmatched reliability and top-tier performance. The result is a magazine extension that adds a functional +5 rounds and improved gas capacity, giving you the edge when split seconds and shot counts matter most. At the heart of this performance version lies a full CNC 6-series aluminum body. Precision-machined from high-quality aluminum, the body provides an outstanding strength-to-weight ratio, excellent corrosion resistance, and long-lasting durability?without weighing down your draw or transitions. The updated performance version also introduces Gas Stabilizer Tubes, a critical innovation that improves liquid-to-gas conversion inside the magazine tank. This ensures a more stable gasification output, directly translating to consistent muzzle velocity and fewer fluctuations during rapid strings of fire. Leak prevention has been addressed with a double O-ring design integrated inside the magazine structure. This dual barrier effectively eliminates the risk of gas leakage, so you can concentrate on your stage plan rather than equipment gremlins. For those who rely on aftermarket parts or prefer a personalized setup, the extension retains compatibility with standard Tokyo Matui-spec magazine base plates and virtually all base plates currently available on
