TacFire MAR047A AR-15 Buffer Tube Kit Mil-Spec 6-Position Black

The TacFire MAR047A AR-15 Buffer Tube Kit delivers mil-spec reliability for AR-15 builds and upgrades at an accessible price point. This complete assembly includes all necessary components for proper buffer system installation and operation.

What Makes This Different

This kit meets military specification dimensions and tolerances, ensuring compatibility with standard mil-spec stocks and components. The 7075-T6 aluminum construction provides the strength-to-weight ratio required for reliable cycling under various conditions. Unlike commercial-spec alternatives, the mil-spec threading and diameter maintain compatibility with the broadest range of aftermarket accessories.

Key Features

• Mil-spec 6-position buffer tube with proper 1.148" outer diameter
• Complete kit includes buffer tube, castle nut, end plate, and buffer spring
• 7075-T6 aluminum construction with Type III hard coat anodizing
• Standard carbine buffer weight for reliable cycling with 5.56/.223 ammunition

• Compatible with all mil-spec carbine stocks and accessories
• Includes staking notches for proper castle nut installation

The mil-spec dimensions ensure consistent lockup and proper headspace with standard bolt carrier groups. Competition shooters benefit from the precise tolerances that eliminate buffer tube wobble, while tactical users rely on the proven durability under high round counts. The hard coat anodizing resists wear from repeated stock adjustments and environmental exposure.
