The 2A Armament Builder Series AR-15 Spring and Detent Kit provides the essential small components required to complete or maintain a high-performance lower receiver with professional-grade reliability. Whether you are assembling a new custom firearm from a stripped lower or performing routine maintenance on a hard-use duty rifle, having precision-engineered hardware is critical for reliable mechanical operation. This kit is specifically designed for armorers and DIY enthusiasts who demand consistent performance and positive engagement from their safety selectors, bolt catches, and takedown pins.

Each component in the 2A Armament Builder Series AR-15 Spring and Detent Kit is manufactured to strict tolerances to ensure a perfect fit within standard Mil-Spec or high-end billet receiver geometries. The high-tensile springs offer the exact resistance needed for positive tactile feedback, ensuring that your fire control and takedown components stay securely in place until intentionally moved. These precision-machined detents facilitate smooth movement without binding or grit, while the high-quality materials resist fatigue and environmental corrosion over thousands of operational cycles.

This comprehensive kit is a mandatory staple for any armorer's workbench, offering a convenient and cost-effective solution for those looking to buy a 2A Armament Builder Series AR-15 Spring and Detent Kit for their next specialized project. It is fully compatible with standard AR-15, M4, and M16 platforms, making it a versatile choice for a wide range of defensive, hunting, or competition-focused builds. Keeping these small but vital parts on hand ensures that a lost spring or worn detent never results in unnecessary downtime at the bench or while out in the field.
