Stronger Base For Eliminating Extractor Bounce
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 10-paks.
