Aim Sports XDB15PSTOC Mil-Spec Buffer Tube AR-15 M4 Black Anodized

The Aim Sports XDB15PSTOC Buffer Tube delivers reliable mil-spec performance for AR-15 and M4 platform builds. This black anodized aluminum component ensures proper bolt carrier group cycling while maintaining the dimensional standards required for consistent stock compatibility.

What Makes This Different

Mil-spec threading and internal dimensions guarantee compatibility with standard carbine buffer springs and weights. The Type III hard anodized finish provides superior corrosion resistance compared to basic phosphate coatings. Internal diameter measures exactly 1.168 inches, meeting military specifications for proper buffer travel and compression.

Key Features

• Mil-spec 1.168-inch internal diameter for standard buffer compatibility
• 6061-T6 aluminum construction with Type III hard anodized finish
• Standard carbine length threading (1.14x16 TPI)
• Castle nut threads machined to military specifications
• Drain hole prevents moisture accumulation
• Compatible with all mil-spec collapsible stocks
• Black anodized finish matches most AR-15 receivers

This buffer tube handles the repeated stress of semi-automatic cycling without dimensional changes or thread wear. The precision-machined interior surface ensures smooth buffer travel during rapid fire sequences. Law enforcement agencies and competitive shooters rely on mil-spec components for consistent function across different ammunition weights and environmental conditions.
