The Kak Industry K-SPEC AR-15 H3 Buffer Tube Kit is a complete recoil management system built for AR-15 owners who want smoother shooting without overcomplicating their build. This kit pairs a 5.5 oz H3 K-SPEC buffer with a flatwire spring and mil-spec carbine buffer tube, addressing the core frustrations of standard buffer setups: excessive muzzle rise, bolt bounce, and uncontrolled recoil impulse. Whether you're running a mid-length or carbine-length AR for hunting, tactical drills, or competitive shooting, the captured compression design absorbs energy more effectively than basic alternatives while keeping parts simple and durable.
Kak Industry engineered the K-SPEC system to deliver genuine recoil reduction without exotic materials or complex failure points. The flatwire spring resists kinking and maintains consistent performance through thousands of rounds. The buffer tube itself is mil-spec, ensuring compatibility with standard receiver extensions and furniture across the AR platform. The kit includes an install tool, so you're ready to swap it in without hunting down extra hardware.
Built entirely in the USA, this kit is backed by Kak Industry's reputation for no-nonsense, American-made parts. The H3 weight is the heavier option in the K-SPEC lineup, making it a solid choice if you're running a rifle that tends to beat you up or if you want maximum felt recoil control. If you've dealt with cheap buffer setups that rattle loose or springs that lose their snap, this kit represents a meaningful upgrade in reliability and performance.
| Brand | Kak Industry |

| Buffer Weight | 5.5 oz (H3) |
| Spring Type | Flatwire |
| Buffer Tube Spec | Mil-spec carbine |
| Color | Black |
| What's Included | H3 K-SPEC buffer, flatwire spring, carbine buffer tube, install tool |
| Made In | USA |
Yes. The kit features a mil-spec carbine buffer tube, which is the standard size for most AR-15 rifles and compatible with all standard receiver extensions and furniture on the market.
The H3 designation refers to the 5.5 oz weight of the buffer. Heavier buffers slow bolt carrier movement and reduce felt recoil more aggressively. The H3 is the heavier option in the K-SPEC lineup, best suited for maximum recoil control or rifles that cycle hard.
Yes. The kit includes the H3 buffer, flatwire spring, carbine buffer tube, and an installation tool, so you have all the parts and hardware needed to complete the swap.
Flatwire springs resist kinking and coil binding better than traditional wound springs, maintaining consistent performance and reliability through extended use without losing tension or developing weak spots.
