The KWA line up of rifs are fantastic, but their stocks lack space to fit that majority of batteries...
Enter the Project Airsoft Battery Extension Unit for KWA Rifs.
Our Battery Extension Unit increases the battery storage area by 43mm which may not sound like much, but that's over 30% extra space for you to fit in the battery of your choosing.
It fits and clips into place just like the original cap which comes with the rif and does not effect your usage of the rif at all (except now you can use the batteries you want!).
Note: Available in Tan or Black. Shade of colour may vary.
