The PTS Extended Battery Storage Butt Pad is a standalone accessory that gives the EPS-C butt stock the capability to fit a LiPo battery within the extended butt pad space. This accessory expands the EPS-C stock’s capability to be used for different airsoft rifle systems that lack buffer tube battery space such as the KWA ERG/AEG 3.0/3.0+ and the Tokyo Marui Next Gen Recoil System.   The EPS-C with the Extended Butt Pad is also perfect for users who prefer slender or minimalist stocks but whose AEG’s have an inline MOSFET inside the buffer tube which leaves extremely limited or no space within the rifle’s buffer tube to insert a battery. The butt pad inner battery storage size is approximately 105 x 20 x 15mm and capable of accommodating most 11.1 buffer tube type LiPo batteries.
