One of the many uses of the Ruger 10/22 Takedown design is as a compact survival tool that can remain ready in a prepper pack until needed. However, to ensure that your rimfire rifle works in these survival situations, having spares like the Powder River Precision Survivor Series 10/22 Ejector on hand is essential. Each Powder River Precision Survivor Series 10/22 Ejector is machined from stainless steel and is heat-treated to a Rockwell Hardness of 40 RCH. In addition to the spare ejector, the unit also comes with an additional extractor, which is another component on the 10/22 Takedown that can break during disassembly, if the rifle is taken down improperly.
