KAK Industry A5 Style 9-Position Buffer Tube - 515-0604-001

Enhance the performance and customization of your AR-15 or AR-10 build with the KAK Industry A5 Style 9-Position Buffer Tube. This precision-engineered receiver extension delivers the advantages of a rifle-length buffer system in a compact, adjustable design, promoting smoother cycling and reduced recoil impulse for improved shooter comfort and follow-up shot accuracy.

Key Features

• Extended A5-Style Design: Longer than standard carbine buffer tubes to accommodate rifle-length AR-15 buffer springs and A5-style buffers, providing a more controlled recoil impulse compared to traditional carbine setups.
• 9-Position Adjustability: Offers versatile stock positioning for a customized length of pull, accommodating shooters of various sizes while maintaining a compact profile.
• Premium Construction: Machined from high-quality 7075-T6 aluminum with a durable black military hard coat anodized finish for excellent corrosion resistance and long-term durability in demanding conditions.
• Standard Compatibility: Works with mil-spec end plates and castle nuts for straightforward installation on most AR platforms; uses standard milspec components.

Why Choose the KAK Industry A5 Buffer Tube?

Standard carbine buffer tubes can result in harsher recoil and less reliable cycling, particularly in suppressed or over-gassed configurations. This A5-style tube addresses those pain points by enabling the use of a rifle-length spring in a shorter package, minimizing bolt bounce and optimizing function for consistent performance during range sessions or tactical use. The added positions provide more adjustment options than many competing A5 tubes.

Built to mil-spec standards with rolled threads where applicable and precision machining, this buffer tube ensures reliable fit and function. Its lightweight yet robust design makes it an ideal choice for custom builds seeking enhanced ergonomics without added bulk.

Common Questions

Q: What buffer and spring should I use? A: For AR-15 builds, pair with A5-style buffers and rifle-length AR-15 buffer springs only. AR-10 builds can use standard AR-15 length buffers with appropriate components.

Q: Is this compatible with my mil-spec stock and end plate? A: Yes, it uses standard mil-spec end plates and castle nuts for broad compatibility with most AR-pattern lowers and stocks.
