The PTS Extended Battery Storage Butt Pad is a purpose-built accessory that transforms your EPS-C stock into a self-contained power solution. If your airsoft rifle platform lacks dedicated buffer tube battery space, this extension delivers a practical workaround without compromising ergonomics or handling.
Key Features
- Integrated LiPo battery storage within extended butt pad – eliminates external battery pouches
- Compatible with EPS-C stocks across multiple platforms – KWA ERG, KWA AEG 3.0/3.0+, Tokyo Marui Next Gen Recoil System
- Maintains stock ergonomics – no bulky external solutions required
- Straightforward installation – pairs directly with standard EPS-C assembly
- Practical for milsim and skirmish – clean, integrated appearance
Real-World Use Cases
Milsim operators running Next Gen Recoil platforms, or airsofters upgrading to KWA’s latest generation gearboxes, often face the challenge of tight buffer tube spaces. This butt pad removes that constraint, allowing longer skirmish sessions without swapping external batteries mid-game. Ideal for extended field days where battery accessibility matters.
Technical Specifications
- Design: Extended butt pad with internal battery cavity
- Compatibility: EPS-C stock (KWA ERG, KWA AEG 3.0/3.0+, Tokyo Marui NGRS)
- Battery Type: LiPo (capacity depends on pad dimensions)
- Installation: Drop-in attachment to standard EPS-C assembly
Compatibility & Upgrades
This accessory is specifically engineered for the PTS EPS-C platform. Verify your rifle’s stock compatibility before purchase—it will not fit standard M4 buffer tubes or non-EPS-C systems. Pairs seamlessly with existing EPS-C rail systems and ergonomic controls.
UK Legal & Site Notes
As a passive battery storage accessory, the butt pad carries no restrictions under UK airsoft regulations. Always confirm your site permits the rifle platform you’re upgrading (ERG, Next Gen NGRS, etc.) before attending.
