It is machined from \u003cstrong\u003e4140 steel\u003c\/strong\u003e and finished in a rugged \u003cstrong\u003eblack manganese phosphate\u003c\/strong\u003e coating for long-term wear and corrosion resistance.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe folding mechanism uses a \u003cstrong\u003efull-length locking lug\u003c\/strong\u003e for maximum strength and delivers a solid, positive lock-up in both open and folded positions with no play under recoil. Deployed, the adapter adds \u003cstrong\u003e2.5 inches\u003c\/strong\u003e to the overall length of the host firearm; folded, it adds only \u003cstrong\u003e0.75 inches\u003c\/strong\u003e for the shortest possible carry profile. The complete assembly weighs in at just \u003cstrong\u003e8.4 oz\u003c\/strong\u003e, so it adds meaningful function without bogging down the rear of the receiver.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe included tube accepts any \u003cstrong\u003eMil-Spec\u003c\/strong\u003e carbine stock, pistol stabilizing brace, or compatible accessory, making the MISTAPSF a versatile drop-in upgrade for \u003cstrong\u003eAR-15\u003c\/strong\u003e pattern pistol builds. Per the manufacturer, this adapter is \u003cstrong\u003eintended for use on pistols only and is not a stock\u003c\/strong\u003e - pairing it with an approved pistol stabilizing brace keeps the host legally classified as a pistol while giving the shooter a shouldered platform when needed.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eProudly \u003cstrong\u003emade in the USA\u003c\/strong\u003e by Midwest Industries, a respected American manufacturer of tactical rifle accessories, the MISTAPSF delivers the fit, finish, and lock-up that demanding shooters expect from a premium side-folder.\u003c\/span\u003e\u003c\/p\u003e","brand":"Midwest Industries","offers":[{"title":"Default Title","offer_id":55479653433666,"sku":"133750","price":146.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_fab6b8f0-cb38-4a14-801a-05e9a84492f3.png?v=1785578249","url":"https:\/\/centerfiresystems.com\/products\/midwest-industries-mistapsf-buffer-tube-with-side-folding-adapter-black-4140-steel","provider":"Centerfire Systems","version":"1.0","type":"link"}
