Timber Creek Outdoors ARBTKB Buffer Tube Kit Blue Anodized AR-15

The Timber Creek Outdoors ARBTKB Buffer Tube Kit delivers enhanced aesthetics and reliable function for AR-15 builds with its distinctive blue anodized finish. This complete buffer system provides all necessary components for proper bolt carrier cycling while adding a custom appearance that stands out from standard mil-spec parts.

What Makes This Different

Unlike standard black buffer tubes, this kit features Type III hard anodizing in vibrant blue that resists wear and corrosion better than basic coatings. The precision-machined 7075-T6 aluminum construction meets mil-spec dimensional tolerances while the complete kit eliminates the need to source individual buffer components. The anodized finish maintains color consistency even under heavy use and cleaning solvents.

Key Features

• Complete 6-position buffer tube assembly with carbine-length extension
• Type III hard anodized blue finish for superior durability and appearance
• 7075-T6 aluminum construction with mil-spec threading and dimensions
• Includes buffer spring, carbine buffer, and castle nut with end plate
• Compatible with all mil-spec AR-15 lower receivers and carbine stocks
• Precision-machined internal surfaces for smooth bolt carrier operation
• Staked castle nut design prevents loosening during operation

This buffer system maintains consistent bolt carrier velocity across various ammunition weights and powder charges. The included H-weight carbine buffer provides optimal cycling with standard 5.56/.223 loads while the chrome silicon buffer spring delivers thousands of compression cycles without performance degradation. The anodized finish withstands exposure to cleaning chemicals, weather conditions, and high round counts without color fading.
