Designed to drop onto any standard \u003cstrong\u003eAR-15 lower receiver\u003c\/strong\u003e, this upper brings gas-piston reliability, reduced fouling, and cooler-running operation to the familiar AR manual of arms.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eAt the heart of the ARAK-21 is a \u003cstrong\u003e16-inch\u003c\/strong\u003e barrel mated to a \u003cstrong\u003edetented 5-position gas regulator\u003c\/strong\u003e that allows the shooter to tune cycling for everything from suppressed fire to commercial and military-grade 5.56\/.223 ammunition. The \u003cstrong\u003efree-float handguard\u003c\/strong\u003e is outfitted with three full-length aluminum Picatinny rails, giving a continuous mounting surface for optics, lights, lasers, and forward grips. The barrel is finished off with the \u003cstrong\u003eMuzzLok\u003c\/strong\u003e muzzle device on a standard \u003cstrong\u003e1\/2x28\u003c\/strong\u003e thread pitch, ready for your preferred suppressor or muzzle accessory.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe upper ships finished in a distinctive \u003cstrong\u003etungsten\u003c\/strong\u003e coating that gives the receiver and components a unique gunmetal-gray appearance while adding corrosion and wear resistance for hard field use. Whether you are building a dedicated host upper, a training rifle, or a suppressed tactical setup, the ARAK-21 gives you the modularity of the AR-15 platform with the durability and cleanliness benefits of a true piston-driven action. This listing is for the \u003cstrong\u003ecomplete upper assembly only\u003c\/strong\u003e; a compatible AR-15 lower receiver is required to complete the firearm.\u003c\/span\u003e\u003c\/p\u003e","brand":"Faxon Firearms","offers":[{"title":"Default Title","offer_id":55051016700226,"sku":"182007","price":994.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_4f132e8d-626f-404f-a441-93f1ee0c5ffc.png?v=1784716325","url":"https:\/\/centerfiresystems.com\/products\/faxon-firearms-arak-21-5-56x45mm-nato-16-gas-piston-complete-ar-15-upper-tungsten","provider":"Centerfire Systems","version":"1.0","type":"link"}
