Why Choose the KAK A2 Buttstock Kit?

The A2 stock has been trusted on the M16A2 and countless AR15 builds for decades. Its longer length of pull, durable construction, and integrated storage compartment make it a favorite for shooters who value tradition and stability. Compared to adjustable stocks, the A2 provides rock-solid consistency and improved cheek weld, making it ideal for precision and retro builds alike.

A1 vs A2 Buttstock: Key Differences

• Length – The A2 is about 5/8" longer than the A1, offering an extended length of pull.

• Storage – A2 stocks include a trapdoor storage compartment.

• Authenticity – A1 stocks suit Vietnam-era builds, while the A2 is standard for M16A2 and later clones.
