This 10-pack provides spares for multiple builds or replacements for worn or lost retainers—a common occurrence during field stripping, maintenance, or parts installation. Each retainer includes its spring for complete functionality.\u003c\/p\u003e\u003cp\u003eMachined from steel with a phosphate finish for corrosion resistance, these retainers are drop-in replacements requiring no gunsmithing. Installation is straightforward: insert the spring into the retainer hole in the lower receiver, compress with a punch, and slide the retainer into place. The 10-pack format is ideal for armorers, gunsmiths, or builders managing multiple AR platforms.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Buffer Retainer with Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 Pattern Rifles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e 10 Buffer Retainers, 10 Springs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luth-AR","offers":[{"title":"Default Title","offer_id":47938460745983,"sku":"LUTHLR-01A-10","price":25.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1290403.jpg?v=1766516669","url":"https:\/\/doublestackstore.com\/products\/luth-ar-buffer-retainer-w-spg-10pk","provider":"Double Stack Store","version":"1.0","type":"link"}
