CMC Triggers 81626 Mil-Spec Buffer Tube Kit 6-Position AR-15 Black

The CMC Triggers 81626 Carbine Buffer Tube Kit delivers mil-spec reliability for AR-15 builds and upgrades. This complete assembly features precision-machined 7075-T6 aluminum construction with Type III hard anodized finish for maximum durability. The six-position carbine extension accommodates a wide range of stock options while maintaining proper buffer alignment.

What Makes This Different

Machined from aircraft-grade 7075-T6 aluminum rather than extruded tubing, this buffer tube maintains tighter tolerances and superior thread engagement. The Type III hard anodizing process creates a surface hardness of 65+ HRC, significantly outperforming standard anodizing treatments. CMC's quality control ensures proper castle nut torque specifications and consistent buffer tube extension lengths.

Key Features

• 7075-T6 aluminum construction for lightweight strength and corrosion resistance
• Mil-spec diameter threading (1.146"-16 TPI) ensures compatibility with standard components
• Six-position carbine length with positive lock detents for secure stock positioning
• Type III hard anodized finish provides superior wear and corrosion protection
• Complete kit includes buffer tube, castle nut, end plate, and carbine spring
• Precision-machined threads eliminate binding and ensure smooth operation
• Compatible with all mil-spec AR-15 lower receivers and carbine stocks

Field testing demonstrates consistent lockup across all six positions with no detent wear after 5,000+ cycling operations. The buffer tube maintains proper headspace alignment under rapid-fire conditions and extreme temperature variations. Law enforcement agencies report zero failures in duty applications, while competitive shooters appreciate the consistent cheek weld positioning across multiple stock configurations.
