LBE Unlimited ARBRP Buffer Retaining Pin 10-Pack AR-15 Black Steel

The LBE Unlimited ARBRP Buffer Retaining Pin 10-Pack provides essential replacement parts for AR-15 platform maintenance and builds. These precision-manufactured steel pins ensure reliable buffer tube retention during extended firing cycles and field conditions.

What Makes This Different

Unlike standard retaining pins that may bend or break under stress, these black steel pins feature enhanced metallurgy for superior durability. The 10-pack quantity eliminates single-point failures during critical maintenance operations. Each pin maintains precise tolerances to ensure proper fit within mil-spec lower receivers and buffer extension assemblies.

Key Features

• Heat-treated black steel construction resists deformation under repeated stress cycles
• Mil-spec dimensions ensure compatibility with all standard AR-15 lower receivers
• 10-piece pack provides multiple replacements for armorers and serious shooters
• Corrosion-resistant black finish withstands harsh environmental conditions
• Precision-ground ends facilitate smooth installation and removal
• Spring-tempered steel maintains elasticity through thousands of compression cycles
• Compatible with carbine, rifle, and pistol buffer systems

These retaining pins perform reliably across temperature extremes from -40°F to 160°F, maintaining buffer tube security during rapid-fire sequences and adverse conditions. Law enforcement armorers stock these pins for patrol rifle maintenance, while competitive shooters rely on them for match preparation. The enhanced steel composition prevents the pin fatigue common with standard pins during high round-count training sessions.
