The J P Enterprises Silent Capture Spring Buffer Retainer Pin and Spring is a small hardware set from J P Enterprises (brand part no. JPSCS-BRP) that replaces the standard AR-15 buffer retainer pin and spring used to hold the buffer captured in the lower receiver. It is a wear item worth keeping on hand for any AR builder maintaining a J P Enterprises Silent Captured Spring system or a standard mil-spec buffer setup, since a weak retainer spring can let the buffer walk out of position.

Frequently Asked Questions

What does the retainer pin do? It locks the buffer retainer spring in the lower receiver, which in turn holds the buffer captured in place under spring tension.

When should this be replaced? If the retainer spring weakens and lets the buffer walk forward or rattle out of position, replacing this pin and spring restores proper retention.
