LBE Unlimited AR Buffer Retaining Pin Spring 10-Pack – AR-15/AR-10

The LBE Unlimited AR Buffer Retaining Pin Spring 10-Pack provides replacement springs for the buffer retaining pin system in AR-15 and AR-10 platform rifles. These springs maintain proper tension on the buffer retaining pin, which prevents the buffer from dislodging during disassembly or when the upper and lower receivers are separated. This is a high-wear component that can weaken or break over time, especially with frequent field stripping, making spares essential for armorers and high-volume shooters.

Constructed from heat-treated steel wire, these springs are designed to deliver consistent tension throughout their service life. Installation is straightforward but requires careful attention—the spring must be properly compressed during reassembly to avoid loss or damage. This 10-pack provides a cost-effective solution for maintaining multiple firearms or keeping spares on hand for training courses and armorer work.
