It seems every time I pull the extractor out of my bolt, the extractor buffer is all chewed up. I guess I'm not checking on that small part often enough. As we know though, even the small parts can leave you in a bad spot.
Tough, dense rubber insert replaces factory buffer inside the extractor spring to prevent “extractor bounce” that can occur in rapid-fire conditions. Insert keeps the extractor from losing contact with casings and reducing faulty ejection of the spent casing. Sold in a pack of 10 for $14.
