Brownells Rivet Stake Tool Set Features The Brownells Rivet Stake Tool Set gives armorers and 870 owners two punches each ground for a specific step of the Remington 870 s two-step ejector rivet. The first punch carries a 0.070 inch hole in its face letting it fasten the ejector housing to the receiver using the rivet s lower portion. The second punch then secures the ejector spring within the housing using the upper portion of the same rivet. Working through each step in sequence keeps the installation precise and avoids damaging the housing or spring in the process. Machined from steel and finished in black the punches are built for repeat use on the bench without excessive wear. Each measures roughly 3.5 inches long giving enough leverage and control for accurate staking work. This two-punch pairing is the base version of Brownells 870 staking tools giving armorers and 870 owners the essential punches needed to service the ejector system correctly. For anyone maintaining Remington 870 shotguns regularly this set is a practical purpose-built addition to a gunsmithing bench.
