Tichá vratná pružina Gen 2 pro AR-15 - H2

JP JPSCS2-15H2 is a Silent Captured Spring Gen 2 system designed for the AR-15 platform, replacing the classic combination of buffer + recoil spring + buffer retainer with a single compact module. The H2 version uses a heavier weight configuration (2× tungsten + steel), bringing it closer to the characteristics of an H2 buffer and making it suitable for tuning firearms with higher gas pressure.

The system is designed to significantly reduce noise and vibration during the bolt cycle – it eliminates the typical "sproing" sound of the spring in the buffer tube and improves the smoothness of operation.

The Gen 2 design brings improved guidance, reduced friction and modular weights that can be swapped to fine-tune firearm behavior according to configuration (barrel, gas system, suppressor, ammunition).

The H2 variant is recommended especially for:

• short-barreled and carbine AR systems
• overgassed firearms
• use with a suppressor
• SBR / sporting and dynamic shooting

The system is a drop-in solution and requires no permanent modifications to the firearm.

Key features:

• complete replacement for buffer and spring (AR-15)
• Gen 2 Silent Captured Spring system
• H2 configuration (increased weight – tungsten + steel)
• significant noise reduction ("no sproing")
• smoother bolt operation and reduced vibration
• modular system with adjustable springs/weights
• suitable for SBR, suppressed and sporting configurations
• drop-in installation with no firearm modifications
