Timber Creek Outdoors ARBTBL Mil-Spec Buffer Tube - AR-15 Platform

The Timber Creek Outdoors ARBTBL Buffer Tube delivers mil-spec reliability for AR-15 builds requiring precise dimensional tolerances and consistent cycling performance. This hardcoat anodized aluminum component maintains the exact specifications demanded by military contractors while providing enhanced durability for civilian applications.

What Makes This Different

Unlike commercial-spec alternatives, this mil-spec buffer tube features the smaller outer diameter and precise internal dimensions that ensure proper stock fitment and reliable bolt carrier cycling. The hardcoat anodizing process creates a surface hardness of 65+ HRC, significantly exceeding standard Type II anodizing for superior wear resistance. Threading meets exact TDP specifications for consistent torque values and secure castle nut installation.

Key Features

• Mil-spec outer diameter (1.146") ensures compatibility with military-pattern stocks
• 6061-T6 aluminum construction with hardcoat anodizing for maximum durability
• Precise internal bore dimensions maintain consistent buffer spring compression
• Standard carbine length threading (1.17"-16 TPI) for universal compatibility
• Drain hole positioned to prevent moisture accumulation during field use
• Castle nut notches machined to exact specifications for proper staking
• Matte black finish provides non-reflective surface suitable for tactical applications

Field testing demonstrates reliable cycling across temperature ranges from -40°F to 160°F without dimensional changes that could affect function. The hardcoat anodizing resists corrosion in marine environments and maintains dimensional stability under rapid-fire schedules. Competition shooters report consistent lock-up and smooth cycling through high round counts, while law enforcement agencies specify this component for duty rifle builds requiring maximum reliability.
