Designed to deliver an excellent balance of size, weight, and performance, it features a 10.3 inch cold hammer forged barrel with a durable black phosphate finish, a rugged 7075-T6 aluminum receiver with black anodized finish, and the proven DD RIS II MK18 quad rail handguard in Flat Dark Earth. This upper receiver group uses Daniel Defense's Bolt-Up System rail design that was rigorously tested prior to fielding by USSOCOM, making it a strong choice for shooters who want reliability, accessory mounting capability, and close-quarters maneuverability. It also includes an independently ambidextrous GRIP-N-RIP charging handle and comes standard with an M16 profile bolt carrier group for a ready-to-install setup.\u003c\/p\u003e\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eComplete Daniel Defense MK18 upper receiver group for AR-15 rifles chambered in 5.56x45mm NATO.\u003c\/li\u003e\n\u003cli\u003e10.3 inch cold hammer forged barrel with black phosphate finish for durability, accuracy, and long service life.\u003c\/li\u003e\n\u003cli\u003eFlat Dark Earth DD RIS II MK18 quad rail handguard with Bolt-Up System tested for USSOCOM use.\u003c\/li\u003e\n\u003cli\u003e7075-T6 aluminum upper receiver with black anodized finish for strength and corrosion resistance.\u003c\/li\u003e\n\u003cli\u003eIncludes M16 profile bolt carrier group and ambidextrous GRIP-N-RIP charging handle for a complete, high-performance upper assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Daniel Defense\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e MK18 Upper Group\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 2300408013011\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 852548002592\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlatform Fit:\u003c\/strong\u003e AR-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 5.56x45mm NATO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 10.3 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel Type:\u003c\/strong\u003e Cold Hammer Forged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel Finish:\u003c\/strong\u003e Black Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel Material:\u003c\/strong\u003e Chrome Moly Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReceiver Material:\u003c\/strong\u003e 7075-T6 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReceiver Finish:\u003c\/strong\u003e Black Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandguard:\u003c\/strong\u003e DD RIS II MK18 Quad Rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandguard Color:\u003c\/strong\u003e Flat Dark Earth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharging Handle:\u003c\/strong\u003e Ambidextrous GRIP-N-RIP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Carrier Group:\u003c\/strong\u003e M16 Profile Included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Block:\u003c\/strong\u003e Low Profile\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMuzzle:\u003c\/strong\u003e Flash Suppressor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSight Configuration:\u003c\/strong\u003e Flat Top \/ Optic Ready\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
