Armaspec H2 4.7oz Stealth Recoil Spring Carbine Buffer System Bundle

Armaspec H2 4.7oz Stealth Recoil Spring Carbine Buffer System Bundle | SRS 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 self-contained captive spring technology. This bundle includes the H2 buffer weighing 4.7 oz with integrated captured spring that eliminates buffer spring noise, mil-spec heavy-duty aluminum 6-position carbine buffer tube, receiver end plate, and phosphate-finished castle nut. The H2 weight configuration is optimized for suppressed rifles, overgassed systems, SBRs, AR pistols, and competition applications, providing smoother cycling characteristics and faster follow-up shot capability.

Key Features

• SRS H2 Captured Spring Buffer: Self-contained design eliminates buffer spring twang and metallic noise during cycling

• 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
• Mil-Spec 6-Position Buffer Tube: Heavy-duty aluminum construction with standard carbine adjustment capability
• Complete Installation Bundle: Includes buffer tube, H2 buffer, receiver end plate, and phosphate castle nut
• Drop-In Compatibility: Straightforward installation with standard AR-15 lower receivers without gunsmithing
• Competition and Tactical Ready: Improved reliability and faster follow-up shots through optimized weight and noise reduction

Perfect For

• Suppressed AR-15 builds requiring additional buffer mass and noise reduction
• Overgassed systems, SBRs, and pistol configurations benefiting from H2 buffer weight
• Competition rifles seeking faster split times through improved recoil management
• Tactical applications where reduced mechanical noise improves operational stealth
• Gunsmiths and builders looking for complete buffer system bundles with versatile H2 weight

Self-Contained Captive Spring Technology

The Armaspec SRS 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.

H2 Weight for Versatile Applications

The H2 weight configuration at 4.7 oz provides balanced buffer mass suitable for a wide range of AR-15 configurations. This weight offers improved recoil management over standard carbine buffers while remaining versatile enough for both suppressed and unsuppressed applications. The H2 mass is effective in suppressed builds where moderate back pressure benefits from additional buffer weight, overgassed short-barreled configurations requiring smoother cycling, and competition rifles seeking reduced recoil impulse for faster follow-up shots. This versatility makes the H2 a popular choice for builders seeking a single buffer solution across multiple build types.

Enhanced Recoil Control and Follow-Up Speed

The combination of H2 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 across varied ammunition types and shooting conditions.

Complete Mil-Spec Bundle with Drop-In Installation

This bundle includes all essential components for complete buffer system installation: heavy-duty aluminum mil-spec 6-position carbine buffer tube, SRS H2 captured spring buffer, 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.
