Engineered for precision and reliability in ultra-compact AR builds, the Battle Arms VERT PDW Compact Stock System – Buffer Spring delivers the performance needed for demanding tactical applications. This specialized recoil spring integrates seamlessly with the patented VERT buffer system, enabling standard M16 bolt carriers to function flawlessly in minimized receiver extensions while minimizing bolt bounce and enhancing overall cycling consistency.
Key Features
- Patented compact design optimized for PDW stock systems with a fully collapsed length of just 4.8 inches
- Dual-spring arrangement that dampens bolt carrier movement for smoother, more reliable operation, including in full-auto configurations
- High-quality stainless steel construction for durability and consistent tension across thousands of cycles
- Caliber-specific tuning (5.56/.223 compatible) to match the VERT GEN2 PDW stock requirements
Benefits for Tactical Shooters

This buffer spring solves that pain point by supporting a standard BCG in an extremely compact package, reducing overall weapon length without sacrificing function. Shooters benefit from improved recoil management, reduced wear on components, and dependable feeding in high-stress scenarios.
