The LBE Unlimited AR-15 Buffer Retaining Pin Springs (brand part no. ARBRPS) are a 10-pack of silver steel springs sized for the standard AR-15 buffer retainer pin. This small spring sits behind the buffer retainer pin in the lower receiver, keeping tension so the pin holds the buffer and action spring in place during every cycle. It is a high-wear part that armorers replace routinely during maintenance, so a 10-pack is a practical way to stock spares for a shop or a personal collection of builds. The silver steel finish matches factory replacement springs for a correct look and consistent feel.
