JP Enterprises AR-15 Silent Captured Springs | Gen 2

JP Enterprises Gen 2 Silent Captured Spring system replaces the traditional AR buffer and spring assembly with a self-contained recoil management system engineered to reduce spring noise, vibration, and friction during cycling. The captured guide rod design eliminates the characteristic buffer spring “twang” commonly associated with standard AR buffer systems while providing a smoother cycling impulse and more refined operating feel.

Choose the best Gen 2 Silent Captured Spring configurations for both AR-15 and AR-10/LR-308-pattern rifles. Available options include standard and H2 weighted versions along with Builder Kit variants that allow additional tuning flexibility for rifles requiring customized recoil tuning or gas-system balancing.

The Gen 2 design incorporates an aluminum guide rod assembly, modular weighted buffer architecture, and replaceable bumper components for improved durability and serviceability. Standard-weight variants are suitable for a broad range of properly configured AR-15 and AR-10 rifle setups, while H2 variants add additional reciprocating mass for rifles that benefit from heavier buffer characteristics.

Builder Kit models provide additional tuning flexibility for shooters configuring rifles around suppressor use, alternative gas-system lengths, competition-oriented recoil characteristics, or specialized ammunition setups. The captured assembly design also simplifies installation and maintenance compared to conventional buffer spring systems while maintaining compatibility with standard receiver extension configurations when properly matched to the platform.

The AR-15 Silent Captured Spring variants are intended for gas-operated AR-15 rifles across multiple calibers. Standard JPSCS systems are not compatible with 9mm blowback AR platforms or solid weighted blowback carrier systems. Large-frame AR-10 variants are designed for compatible AR-10/LR-308-type rifle configurations, though platform-specific compatibility should always be verified before installation due to dimensional variation among large-frame receiver sets and carrier systems.

Available Options

• JPSCS2-15: Standard-weight Gen 2 Silent Captured Spring for AR-15 rifles. Designed for most standard gas-operated AR-15 carbines and rifles using conventional buffer weights and gas-system configurations.
• JPSCS2-15-H2: Heavy H2-weight Gen 2 Silent Captured Spring for AR-15 rifles. Adds additional reciprocating mass for rifles that may benefit from heavier buffer characteristics, including some suppressed setups or overgassed configurations.
• JPSCS2-15K: AR-15 Builder Kit version with additional tuning springs for shooters who want to fine-tune recoil impulse and cycling behavior around specific ammunition, suppressor use, or gas-system setups.
• JPSCS2-15K-H2: Heavy H2 Builder Kit for AR-15 rifles. Combines the heavier H2 mass configuration with additional tuning springs for expanded recoil and cycling adjustment capability.
• JPSCS2-10: Standard-weight Gen 2 Silent Captured Spring for AR-10/LR-308-pattern rifles. Designed for compatible large-frame gas-operated rifle configurations.
• JPSCS2-10-H2: Heavy H2-weight Gen 2 Silent Captured Spring for AR-10/LR-308-pattern rifles requiring additional reciprocating mass or heavier operating characteristics.
• JPSCS2-10K: Builder Kit version for AR-10/LR-308-pattern rifles that includes additional tuning springs for configuring recoil behavior around different gas-system lengths, ammunition types, or suppressor setups.
• JPSCS2-10K-H2: Heavy H2 Builder Kit for AR-10/LR-308-pattern rifles, combining heavier operating mass with additional tuning spring options for maximum adjustment flexibility.
