The Kak Industry K-Spec AR-15 H1 buffer and spring kit is a purpose-built recoil management system for carbine-length AR platforms. Built on a captured compression design, this 3.8oz H1 buffer absorbs recoil energy and reduces muzzle rise without relying on complex, wear-prone components. Paired with Kak's flatwire spring, the kit delivers a straightforward drop-in upgrade that tightens your rifle's behavior—smoother felt recoil, less bolt bounce, and a flatter sight picture through the shot cycle. Whether you're running a 5.56, .308, or any standard carbine-length AR, this kit keeps things simple and effective.
Kak Industry engineered the K-SPEC system as a value-focused alternative to expensive, complicated buffer solutions. The flatwire spring works in tandem with the captured buffer to manage the bolt's return stroke, which directly translates to improved control and faster follow-up shots. The olive drab green finish fits right in with modern rifle aesthetics and stands up to field use. Everything is manufactured in the USA and built to handle a lifetime of shooting.
This complete kit includes the 3.8oz H1 buffer, matched flatwire spring, and an installation tool—no guessing, no extra trips to source parts. Drop-in compatibility means you swap out your existing buffer tube assembly in minutes. If you're building a new upper or refreshing a rifle that's been neglecting recoil management, this is a no-nonsense upgrade that actually makes a difference.

This kit is designed for carbine-length buffer tubes on AR-15 platforms. Confirm your rifle uses a carbine-length tube (not mid-length or rifle-length) before ordering.
This listing is for the H1 at 3.8oz. Kak also offers H2 (4.7oz) and H3 (5.5oz) weights for different shooting scenarios or recoil preferences. Heavier buffers can provide additional recoil mitigation in some setups.
The kit includes the 3.8oz H1 K-SPEC buffer, flatwire spring, and a buffer installation tool. Everything needed for a drop-in replacement.
Installation is straightforward and designed to be a quick swap. The included tool simplifies the process, and no gunsmithing or special knowledge is required—standard AR maintenance skills are sufficient.
