With a 6.5\" barrel length, this upper group packs the full power of 5.56x45mm into a remarkably short package without sacrificing usability or ergonomics. Featuring CMMG's patent-pending direct impingement Compact Action, the entire action and recoil assembly is housed within the upper receiver, reducing bulk and overall length compared to traditional AR pistols. A forward non-reciprocating left-side charger allows the operator to charge the weapon without breaking their shooting position, while the 9.6\" proprietary M-LOK handguard with a full-length top Picatinny rail provides ample accessory mounting locations. The durable Cerakote Armor Black finish offers excellent corrosion resistance, and the included 1913 Picatinny rail end cap replaces the standard lower receiver buffer tube for a more streamlined build. Every CMMG product is backed by a Lifetime Quality Guarantee against material and workmanship defects.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Highlights\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUltra-Compact 5.56mm Platform:\u003c\/strong\u003e A 6.5\" barrel makes this one of the shortest 5.56mm upper groups available, purpose-built for close-quarters pistol configurations.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePatent-Pending Compact Action:\u003c\/strong\u003e Direct impingement design houses the complete action and recoil assembly inside the upper receiver, reducing overall bulk and length versus traditional AR pistol builds.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForward Non-Reciprocating Side Charger:\u003c\/strong\u003e Left-side charging handle enables the shooter to charge the weapon without coming off target, enhancing speed and control.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Gas Block:\u003c\/strong\u003e Allows precise tuning of the gas system for suppressed or unsuppressed shooting and optimizes performance for various ammunition types.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1913 Picatinny Rail End Cap Included:\u003c\/strong\u003e Replaces the standard lower receiver buffer tube, enabling flexible lower receiver compatibility and cleaner pistol builds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e CMMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Armor Black Cerakote\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e MK4\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 6.5\"\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 Blast Compensator\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 Port Location:\u003c\/strong\u003e Pistol\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block:\u003c\/strong\u003e Adjustable .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 9.6\" Proprietary M-LOK\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\u003eUPC:\u003c\/strong\u003e 810097509344\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e CMM55B9331AB\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003e*NFA Rules May Apply: 6.5\" DISSENT upper groups are designed for use in a pistol configuration.
