LBE Unlimited ARTDDS AR-15 Takedown Detent Springs 10-Pack Bronze

The LBE Unlimited ARTDDS AR-15 Takedown Detent Springs deliver consistent retention force for pivot and takedown pins in AR-platform rifles. This 10-pack ensures builders and armorers maintain proper spare inventory for multiple builds or field replacements.

What Makes This Different

These bronze-finished springs provide superior corrosion resistance compared to standard steel variants. The precision-wound coils maintain consistent tension across temperature extremes from -20°F to 150°F. Each spring undergoes heat treatment to achieve optimal spring rate for reliable pin retention without excessive installation force.

Key Features

• Bronze finish resists corrosion and environmental degradation
• Precision-wound coil design maintains consistent 12-15 pound retention force
• Compatible with all mil-spec AR-15, AR-10, and AR-308 lower receivers
• Heat-treated spring steel construction for long-term durability
• 0.375-inch compressed length fits standard detent channels
• 10-piece quantity supports multiple builds or maintenance inventory
• Manufactured to TDP specifications for proper fit and function

Field testing demonstrates reliable performance through 5,000+ pin actuations without spring fatigue or retention loss. These springs maintain proper tension in competition rifles subjected to frequent breakdown for transport and cleaning. Law enforcement armorers report consistent performance across department inventory spanning multiple manufacturers' lower receivers.
