Designed in California around the \u003cstrong\u003eMil-Spec AR-15 and M4\u003c\/strong\u003e pattern, it replaces standard lower-receiver components so the magazine cannot be released or removed without first separating the upper and lower receivers.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe Safe Mag is machined from \u003cstrong\u003e7075-T6 aluminum\u003c\/strong\u003e and finished in a durable \u003cstrong\u003eblack\u003c\/strong\u003e anodized coating for long-term wear resistance. It installs on \u003cstrong\u003eMil-Spec\u003c\/strong\u003e AR-15 and M4 lower receivers that meet the standard pattern.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eWhen the upper and lower are separated during normal field-stripping, the magazine \u003cstrong\u003eautomatically releases\u003c\/strong\u003e - no extra button or pin to push, no tools required. That automatic release is the design's key feature: it lets the shooter still drop the mag for clearing or reloading while the rifle remains in a compliant configuration at all other times.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe CRSM is intended for builders and shooters in states that require a \u003cstrong\u003efixed-magazine\u003c\/strong\u003e AR-platform setup. Install the Safe Mag into your Mil-Spec lower, verify function, and your AR-platform rifle is set up for state-compliant operation with no permanent modifications to the upper required.\u003c\/span\u003e\u003c\/p\u003e","brand":"Cross Armory","offers":[{"title":"Default Title","offer_id":54991718482242,"sku":"30531","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_34c76e21-9cd0-4984-adab-3d23e26f0689.png?v=1784223258","url":"https:\/\/centerfiresystems.com\/products\/cross-armory-crsm-safe-mag-mil-spec-ar-15-black-aluminum","provider":"Centerfire Systems","version":"1.0","type":"link"}
