Armaspec H3 5.6oz Stealth Recoil Spring Carbine Buffer System Bundle

Armaspec H3 5.6oz Stealth Recoil Spring Carbine Buffer System Bundle | SRS GEN4 Captured Spring | Silent Operation | Mil-Spec Components

A comprehensive buffer system engineered for AR-15 platforms, delivering silent operation and enhanced recoil management through Armaspec's SRS GEN4 captured spring technology. This bundle includes the H3 self-contained buffer weighing 5.6 oz with integrated captive spring that eliminates buffer spring noise, mil-spec heavy-duty aluminum carbine buffer tube, receiver end plate, and phosphate-finished castle nut. The H3 weight configuration is optimized for suppressed builds, SBRs, pistols, and overgassed systems, providing smoother cycling characteristics and faster follow-up shot capability.

Key Features

• SRS GEN4 H3 Captured Spring Buffer: Self-contained design eliminates buffer spring twang and metallic noise during cycling
• H3 Weight Configuration (5.6 oz): Optimized buffer mass for suppressed AR-15s, SBRs, pistols, and overgassed tactical carbines
• Standard Carbine Length (3.25"): Compatible with mil-spec carbine buffer tubes and adjustable stocks
• Silent Operation: Captured spring design prevents spring-to-buffer tube contact and associated vibrations
• Heavy-Duty Aluminum Buffer Tube: Mil-spec dimensions with 6-position adjustment capability
• Complete Installation Bundle: Includes buffer tube, H3 buffer, receiver end plate, and phosphate castle nut
• Drop-In Compatibility: Straightforward installation with standard AR-15 lower receivers without gunsmithing
• Overgassed System Optimization: Additional buffer mass manages excessive bolt velocity and back pressure

Perfect For

• Suppressed AR-15 builds requiring additional buffer mass and noise reduction
• Short-barreled rifles (SBRs) and pistol configurations with overgassed characteristics
• Tactical carbines benefiting from reduced mechanical noise and smoother recoil impulse
• Competitive shooters seeking faster follow-up shots through improved cycling characteristics
• Gunsmiths and builders looking for complete buffer system bundles optimized for high-pressure configurations

SRS GEN4 Captured Spring Technology

The Armaspec SRS GEN4 system replaces the traditional loose buffer spring with a self-contained captive spring integrated within the buffer body. This design eliminates the characteristic metallic twang and spring noise heard during cycling by preventing spring-to-buffer tube contact and the associated vibrations. The result is silent mechanical operation that reduces audible distraction for the shooter and minimizes signature in tactical or hunting environments where discretion matters. The captured spring maintains consistent tension across temperature extremes and high round counts without the spring binding or kinking issues associated with standard buffer springs.

H3 Weight for Suppressed and Overgassed Systems

The H3 weight configuration at 5.6 oz provides optimal mass for managing increased bolt velocity from suppressor back pressure or overgassed short-barreled configurations. This additional buffer weight slows bolt carrier velocity, reducing felt recoil impulse, minimizing wear on internal components, and preventing harsh ejection patterns that can damage brass or cause reliability issues. The H3 mass is particularly effective in suppressed builds where elevated back pressure benefits from additional buffer weight to smooth cycling characteristics and maintain consistent ejection patterns across subsonic and supersonic ammunition types.

Enhanced Recoil Management and Follow-Up Speed

The combination of H3 buffer weight and captured spring design delivers smoother recoil impulse and reduced muzzle rise compared to standard carbine buffer systems. The optimized mass slows the reciprocating motion of the bolt carrier group, translating to softer felt recoil and faster sight recovery between shots. This characteristic benefits competitive shooters seeking improved split times and tactical operators requiring rapid target transitions, while maintaining the mechanical reliability expected from mil-spec buffer systems.

Complete Mil-Spec Bundle with Drop-In Installation

This bundle includes all essential components for complete buffer system installation: heavy-duty aluminum mil-spec carbine buffer tube with 6-position adjustment capability, SRS GEN4 H3 captured spring buffer, AR-15/M16 mil-spec receiver end plate, and phosphate-finished castle nut. The mil-spec buffer tube dimensions ensure compatibility with standard carbine stocks and adjustable braces, while the drop-in design integrates with standard AR-15 lower receivers without requiring specialized tools or gunsmithing expertise. The phosphate castle nut finish provides corrosion resistance and secure thread engagement for long-term installation integrity.

Always follow safe firearm handling practices and manufacturer instructions. Verify compatibility with your specific AR-15 lower receiver, gas system length, and stock configuration. Confirm proper buffer system function and cycling reliability before live fire. Ensure castle nut is properly staked after installation. Comply with all applicable federal, state, and local firearms laws.
