Kak Industry
The KAK Industry AR-15 A5-length carbine buffer is a purpose-built bolt carrier group dampener for shooters running A5-compatible AR platforms. Machined from 7075 aluminum and hard coat anodized for corrosion resistance, this 3.8 oz gold-colored buffer delivers the reliability and durability you need in a rifle platform that handles everything from precision range work to field duty. It's 100% American made and engineered to function smoothly with A5-length buffer tubes and rifle-length AR-15 buffer springs—a critical pairing for proper cycling and felt recoil management.
AR builders and shooters often overlook the buffer as a wear item, but it's a crucial component that absorbs bolt carrier energy and affects how your rifle cycles. A5-length buffers offer a different stroke and travel compared to carbine-length systems, making them valuable for certain builds—especially those where you want to fine-tune lock time or accommodate a heavier receiver setup. KAK's no-nonsense design prioritizes function over flash, making it a solid choice for working guns.
Whether you're tuning a new build or refreshing an existing system, this buffer is a straightforward upgrade that won't break the bank. Just confirm your tube and spring compatibility before ordering—it's A5-specific and won't fit standard carbine-length setups.
| Length | A5-length |
| Weight | 3.8 oz |
| Material | 7075 aluminum |
| Finish | Hard coat anodized gold |
| Compatibility | A5-length buffer tubes and rifle-length AR-15 buffer springs |
| Manufacturer | KAK Industry (USA) |
No. This buffer is A5-length specific and requires an A5-length buffer tube and rifle-length buffer spring. It will not fit or function in a standard carbine-length AR platform. Verify your tube and spring length before purchasing.
This buffer weighs 3.8 oz. Buffer weight influences how your bolt carrier cycles—heavier buffers slow down the rearward movement and can reduce felt recoil. For A5-length systems, proper weight selection depends on your specific rifle setup, barrel length, and load preferences.
The gold color is the result of the hard coat anodizing process, which both protects the 7075 aluminum and makes it easy to spot the buffer inside your receiver. It serves both function and identification purposes.
