This 16.10-inch upper features a 6061-T6 aluminum receiver and an M-LOK handguard for lightweight strength and accessory-ready capability. CMMG’s patent-pending direct impingement Compact Action design keeps the action and recoil assembly within the upper receiver, helping reduce overall length and eliminate the need for a traditional buffer tube when used with the included 1913 Picatinny rear end plate. A forward, non-reciprocating side charging handle supports fast manipulation, while the adjustable gas block helps tune the system for suppressed use or different ammunition.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Highlights\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e.22 ARC (Advanced Rifle Cartridge) DISSENT MK4 upper group designed for Mil-Spec compatible lowers\u003c\/li\u003e\n  \u003cli\u003e16.10-inch barrel with 1:7 twist rate for optimized .22-caliber performance\u003c\/li\u003e\n  \u003cli\u003ePatent-pending direct impingement Compact Action stores recoil assembly in the upper for a more compact setup\u003c\/li\u003e\n  \u003cli\u003eForward non-reciprocating side charger for quick operation without disrupting sight picture\u003c\/li\u003e\n  \u003cli\u003eAdjustable gas block and 1913 Picatinny rear end plate for suppression tuning and buffer-tube-free configurations\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\u003eModel:\u003c\/strong\u003e DISSENT MK4 Upper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Complete Upper Receiver Group\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e .22 ARC (Advanced Rifle Cartridge)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 16.10 in\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 6061-T6 Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandguard:\u003c\/strong\u003e M-LOK rail\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCharging Handle:\u003c\/strong\u003e Forward, non-reciprocating side charger (left-side standard on direct-impingement models)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System:\u003c\/strong\u003e Direct impingement with adjustable gas block\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear Interface:\u003c\/strong\u003e 1913 Picatinny rear end plate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Color:\u003c\/strong\u003e Midnight Bronze (Cerakote)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 6.3 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 28B940CMB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 810148627492\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.
