Kak Industry
The Kak Industry Kspec AR15 A5-length H2 buffer tube kit brings a proven recoil management solution to your AR platform build. An A5-length buffer tube offers distinct advantages for shooters running mid-length or rifle-length gas systems who want smoother cycling and reduced felt recoil compared to standard carbine-length setups. This kit pairs the tube with a 5.6 oz H2 buffer—a mid-weight option that balances reliability across a range of ammunition loads without requiring tuning for suppressed or unsuppressed fire.
Kak Industry has built a reputation for quality buffer systems among AR builders and gunsmiths. The H2 buffer weight sits in the sweet spot for shooters who don't want to chase load-specific tuning but still want predictable performance. Whether you're assembling a precision rifle, a duty gun, or a hunting build, an A5 system can help you achieve the reliability and ergonomics your platform deserves.
This is a complete kit, so you get everything needed to install the A5 buffer tube and H2 buffer. Finished in black, it matches standard AR furniture and mil-spec rail systems. Drop it into your build and get back to the range.

An A5-length buffer tube is longer than the standard carbine-length tube and accommodates a longer buffer, which extends the recoil impulse over a greater distance. This typically results in smoother cycling and less felt recoil, especially with mid-length and rifle-length gas systems. Carbine-length tubes are more compact and are optimized for carbine-gas systems.
The H2 (5.6 oz) is a mid-weight buffer designed to work across a broad range of ammunition types and power levels without requiring load-specific tuning. It's heavier than standard carbine buffers (which are typically 3 oz), which slows bolt carrier group travel slightly and reduces wear on components.
Yes, this is a complete kit that includes the A5 buffer tube and H2 buffer. It has everything needed for installation.
The A5-length buffer tube is designed for AR platforms using mid-length or rifle-length gas systems. Verify your rifle's gas system length before purchase to ensure proper fit and function.
