AirTech KWA Ronin TK45 PDW Tanker Battery Extension

Create More Space for Batteries in Your TK45 PDW

At Bullseye Country Sport, one of the most common complaints about the KWA TK45 PDW is battery space. The compact tanker stock is great for CQB, but once you start trying to fit a battery, MOSFET, fuse and wiring into the same compartment, things can get crowded very quickly. The AirTech Battery Extension Unit is designed to solve exactly that problem.

Designed specifically for the KWA Ronin TK45 PDW and Ronin 6 PDW Tanker Stock, this extension creates additional space inside the stock compartment, making it easier to install larger batteries while reducing stress on wiring, connectors and electronic components. By relieving the cramped environment, it helps prevent excessive cable bending and reduces the risk of damaging batteries during installation.

The extension also locks the stock's twin guide rails together, helping eliminate unwanted movement and creating a more solid feel when shouldering the rifle. Despite the additional internal space, the TK45 retains its compact overall profile, making it just as suitable for CQB use as before.

Manufactured from durable nylon, the Battery Extension Unit is designed to blend seamlessly into the original stock design with no modification required. Integrated ventilation channels help maintain airflow around the battery and electronics, reducing heat build-up during use.
