Spikes Tactical SLA500P Pistol Buffer Tube - Black Anodized

The Spikes Tactical SLA500P pistol buffer tube delivers the structural foundation AR pistol builders demand for reliable cycling and consistent performance. This mil-spec component eliminates the guesswork in pistol builds with precise dimensional tolerances and proven durability.

What Makes This Different

Unlike standard carbine buffer tubes, the SLA500P features pistol-specific threading and dimensions optimized for brace attachment points. The 7075-T6 aluminum construction provides 40% greater strength than 6061 alternatives while maintaining the exact weight distribution needed for proper bolt carrier group timing. Hardcoat anodizing penetrates deeper than standard finishes, creating a wear-resistant surface that maintains dimensional integrity through thousands of firing cycles.

Key Features

• 7075-T6 aluminum construction for maximum strength-to-weight ratio
• Mil-spec dimensions ensure compatibility with standard AR-15 components
• Type III hardcoat anodized finish resists wear and corrosion
• Precision-machined threads accept standard pistol braces and buffer assemblies
• Single-point QD sling mount provision for tactical applications
• Proper castle nut threading prevents loosening under recoil stress
• Compatible with standard AR-15 lower receivers and buffer springs

Field testing demonstrates consistent lockup with major brace manufacturers including SB Tactical, Gear Head Works, and Maxim Defense systems. The precise internal diameter maintains proper buffer weight travel for reliable ejection across various ammunition weights from 55-grain varmint loads to 77-grain match bullets. Weather exposure testing confirms the anodized finish maintains corrosion resistance in saltwater environments and extreme temperature variations from -20°F to 140°F.
