Chambered in 5.56x45mm with a 16.1\" barrel and finished in a durable Armor Black Cerakote, this upper group is built on the patent-pending Compact Action Direct Impingement system that houses the entire action and recoil assembly within the upper receiver. The result is a more compact and streamlined platform compared to traditional AR pistols, without sacrificing reliability or performance. Compatible with any mil-spec lower receiver, and bundled with a 1913 Picatinny rail end plate, this upper group gives you the flexibility to run a folding stock for a compact carbine or add accessories for a pistol build. The forward non-reciprocating left-side charging handle enables quick bolt operation without breaking your sight picture.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Highlights\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePatent-Pending Compact Action Direct Impingement System:\u003c\/strong\u003e Entire action and recoil assembly is housed in the upper receiver, reducing bulk and overall length compared to traditional AR pistols.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Gas Block:\u003c\/strong\u003e Fine-tune your gas system for suppressed shooting or preferred ammunition loads, delivering optimal performance in any configuration.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForward Non-Reciprocating Left-Side Charging Handle:\u003c\/strong\u003e Enables rapid bolt operation without breaking your target acquisition or cheek weld.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCMMG 15\" Proprietary Handguard with CMMG ZEROED Muzzle Brake:\u003c\/strong\u003e Provides ample rail space for accessories while the muzzle brake effectively manages recoil for faster follow-up shots.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime Quality Guarantee:\u003c\/strong\u003e Every CMMG product is backed by a Lifetime Quality Guarantee against material and workmanship defects, ensuring long-term reliability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e CMMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e CMM55BC737AB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 810103474314\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e MK4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\/Finish:\u003c\/strong\u003e Armor Black (Cerakote)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 5.56x45mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating System:\u003c\/strong\u003e Compact Action - Direct Impingement\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 16.1\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Twist:\u003c\/strong\u003e 1:7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Contour:\u003c\/strong\u003e MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Material:\u003c\/strong\u003e 4140CM, SBN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Device:\u003c\/strong\u003e CMMG ZEROED Muzzle Brake\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Thread:\u003c\/strong\u003e 1\/2 x 28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block:\u003c\/strong\u003e Adjustable, 0.750\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUpper Receiver:\u003c\/strong\u003e DISSENT 7075 T6 Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandguard:\u003c\/strong\u003e CMMG 15\" Proprietary\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCharging Handle:\u003c\/strong\u003e DISSENT Side Charger - Left\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReceiver Extension:\u003c\/strong\u003e 1913 Picatinny Rail End Cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 25.5\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 5.05 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\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.
