LBE Unlimited MBUF002 Mil-Spec Buffer Tube 6-Position AR-15

The LBE Unlimited MBUF002 Mil-Spec Buffer Tube delivers reliable carbine-length functionality for AR-15 platform rifles. This 6-position buffer tube meets military specifications and accepts standard carbine buffer springs and weights.

What Makes This Different

Unlike commercial-spec tubes, this mil-spec design features the correct 1.146" outer diameter threading that ensures proper fit with genuine military surplus and quality aftermarket stocks. The tube maintains consistent dimensions across its length, preventing binding issues common with off-spec alternatives. Hard-coat anodized finish resists corrosion and wear better than standard Type II anodizing.

Key Features

• Mil-spec 1.146" outer diameter threading for proper stock compatibility
• 6-position adjustment notches for precise length of pull customization
• 7075-T6 aluminum construction with hard-coat anodized finish
• Standard carbine buffer spring and weight compatibility
• Proper castle nut threading and end plate retention groove
• QD sling swivel mounting provisions on select positions
• Drain hole prevents moisture accumulation

Field testing confirms this buffer tube cycles reliably through thousands of rounds without loosening or dimensional changes. The precise machining eliminates the wobble and play that plague budget alternatives. Competition shooters appreciate the consistent cheek weld positions, while tactical users benefit from quick length adjustments when transitioning between gear configurations.
