KAK AR-15 Carbine Buffer and Spring Combo Review

Hands-On with the KAK AR-15 Carbine Buffer and Spring Combo

The KAK AR-15 Carbine Buffer and Spring Combo is a no-frills, budget-friendly option for completing or upgrading your AR-15 lower receiver. Offered by KAK Industry, this combo promises standard mil-spec performance without breaking the bank. I was eager to see if this affordable option could hold its own against more expensive buffer systems after years of experimenting with various AR builds.

I was seeking a reliable and inexpensive buffer and spring combo for a budget AR build. I wanted something that simply worked without needing to pay for fancy features or brand names I didn’t need. My primary AR, built several years back, has a high-end buffer system, so I decided to see if the KAK offering could compete.

Unboxing the KAK AR-15 Carbine Buffer and Spring Combo revealed exactly what I expected: a standard carbine buffer and a chrome silicon spring. The finish on the buffer was basic but clean, and the spring felt adequately strong. The overall impression was one of functional simplicity, with no indication of fancy coatings or finishes.

I recently completed a build with a more expensive spring and buffer from Brownells and another with a Strike Industries buffer system. The KAK system obviously lacked the aesthetic appeal and perceived refinement of those options. My initial excitement wasn’t overwhelming, but I was optimistic that its performance would prove its value.

Real-World Testing: Putting KAK AR-15 Carbine Buffer and Spring Combo to the Test

First Use Experience

I tested the KAK AR-15 Carbine Buffer and Spring Combo at my local outdoor shooting range. The range offers a variety of scenarios, from prone slow-fire to rapid target acquisition drills. I used the KAK combo in a newly built AR-15 chambered in 5.56 NATO, firing a mix of 55-grain and 62-grain ammunition.

The weather was mild and dry during my first range session. The KAK buffer system functioned flawlessly throughout the initial 200 rounds fired. There were no malfunctions or hiccups to report, and the recoil impulse felt consistent with a standard carbine buffer system.

The KAK AR-15 Carbine Buffer and Spring Combo installed easily into my standard carbine buffer tube, and required no specialized tools to assemble. The cycling felt smooth and familiar from the first round. The simplicity of it all was refreshing.

Extended Use & Reliability

After several months of use and approximately 1,000 rounds fired, the KAK AR-15 Carbine Buffer and Spring Combo continues to perform admirably. I haven’t experienced any failures to feed, failures to eject, or other buffer-related issues. The KAK system provides consistent performance.

I haven’t observed any significant wear and tear on the buffer or spring. Visual inspection reveals only minor surface scratches. The system seems well-suited for typical range use and occasional tactical drills.

Cleaning the buffer and spring is straightforward. I simply wipe them down with a lightly oiled cloth after each range session. No special solvents or procedures are required. This system has proved itself to be superior to my initial expectations.
