KAK AR15 Buffer Tube M16 A5 Carbine

KAK Industry A5 Buffer Tube for AR15

The A5-style buffer tube represents a refinement in AR15 ergonomics and reliability. This component serves as the backbone of your rifle's recoil management system, housing the buffer and spring that work together to cycle your action smoothly and consistently.

Key Specifications

• Tube Style: A5 configuration
• Finish: Anodized black
• Platform: AR15 compatible
• Manufacturer: KAK Industry

Important Compatibility Information

The A5-style buffer tube operates on a different principle than standard carbine tubes. It requires:

• A5-compatible buffers only — standard carbine buffers will not function properly
• Rifle-length AR15 buffer springs — do not substitute standard carbine springs

This design delivers a smoother recoil impulse and improved reliability compared to conventional carbine systems, particularly in shorter-barreled builds where felt recoil can be more pronounced.

Why Choose A5?

The A5 system has become the standard for serious AR15 builders who demand consistent performance. The longer spring and heavier buffer combination provides superior reliability and a noticeably softer shooting experience.

Verify your buffer and spring selection before assembly to ensure optimal performance.
