Designed specifically for Gen 4 upper receivers, this all‑black buffer kit delivers smoother cycling, reduced felt recoil, and enhanced reliability for both tactical and competition shooters.

Key Benefits & Features

  • Optimized Recoil Management: The H3 spring’s advanced coil geometry absorbs and disperses recoil forces, providing a softer shooting experience without compromising bolt carrier velocity.

  • Gen 4 Compatibility: Engineered to fit AR‑15 Gen 4 lower receivers, the kit includes a precision‑machined buffer tube, buffer, and spring for a perfect match.
  • All‑Black Finish: The sleek black coating on the buffer tube and spring resists corrosion, reduces glare, and blends seamlessly with tactical builds.
  • Easy Installation: Comes with a complete set of installation hardware and a step‑by‑step guide, allowing a quick swap in under 30 minutes with basic tools.
