Self-Contained Captive Spring Buffer System: Engineered with self-contained captive spring buffer system that integrates buffer and spring into single drop-in component, streamlining installation with no gunsmithing required. The captive spring design eliminates the traditional separate buffer spring that runs the length of the buffer tube, replacing it with internal spring mechanism contained within the buffer body. This innovative design ensures silent operation by effectively eliminating spring noise and twang characteristic of standard buffer springs, facilitating faster follow-up shots without audible distraction. The quiet operation is particularly beneficial for suppressed builds where mechanical noise becomes more noticeable without gunshot masking it.

H3 Heavy Buffer for Overgassed Systems: Weighing 5.6 oz, this H3 heavy buffer provides increased mass compared to standard carbine buffers (3.0 oz) and H1 (3.8 oz) or H2 (4.6-4.7 oz) buffers for optimal performance in suppressed and overgassed systems. The additional weight slows bolt carrier velocity, reducing felt recoil and preventing overly harsh cycling that can cause accelerated wear and reliability issues. This recoil spring excels in recoil management for suppressed ARs where back pressure increases bolt speed, SBRs with shorter gas systems creating higher port pressure, and overgassed factory rifles requiring buffer weight increase for proper cycling characteristics and reduced recoil impulse.

Standard Carbine Length with Mil-Spec Compatibility: The dimensions include standard carbine length of 3.25 inches, making it compatible with mil-spec carbine buffer tubes without requiring extended or pistol-length buffer tubes. This standard sizing ensures universal fitment across AR-15 carbine platforms including standard rifles, SBRs, and AR pistols using carbine buffer systems. The mil-spec compatibility guarantees proper fit and function with commercially available buffer tubes, eliminating fitment concerns and ensuring reliable operation. The drop-in design allows installation by simply removing existing buffer and spring, then inserting the Stealth system.

Optimized for Multiple AR-15 Configurations: Best suited for suppressed ARs where increased back pressure requires heavier buffer and silent operation eliminates mechanical noise, SBRs with overgassed characteristics from shorter barrels and gas systems, AR pistols requiring H3 weight for reliable cycling, competition rifles seeking reduced recoil and faster follow-up shots, and tactical carbines with suppressors where both weight and silent operation provide advantages. The Stealth system brings consistent performance in various shooting conditions, ensuring smooth and reliable shooting experience across multiple AR-15 configurations. The Armaspec Stealth Recoil Spring SRS H3 5.6oz is designed for AR-15 shooters seeking enhanced buffer solutions—combining self-contained captive spring buffer system for silent operation, H3 heavy 5.6 oz buffer weight for overgassed and suppressed systems, standard 3.25-inch carbine length with mil-spec compatibility, drop-in installation requiring no gunsmithing, elimination of traditional buffer spring noise, optimized recoil management, and enhanced shooting stability in a package that delivers quiet mechanical operation, reduced felt recoil, reliable cycling for suppressed builds, and proven performance ideal for AR-15 suppressed configurations, SBRs, AR pistols, competition rifles, tactical carbines, and overgassed systems requiring H3 buffer weight with silent captive spring technology for improved shooting experience.
