Utilizing CMMG's patent-pending Compact Action Direct Impingement system, the entire action and recoil assembly is housed within the upper receiver, yielding a noticeably shorter and lighter package than traditional AR platforms. The 14.5\" barrel comes with the CMMG ZEROED SVD Brake pinned and welded to the muzzle, bringing the overall barrel length to a legally compliant 16.1\" and allowing the use of standard stocks and braces without any NFA SBR registration. Whether you are starting a fresh bufferless build or adding options to an existing DISSENT lower, this upper group delivers outstanding versatility and performance. A forward non-reciprocating reversible side charging handle enables fast bolt manipulation without breaking your target acquisition, and an adjustable 0.750\" gas block lets you dial in the gas system perfectly for suppressed shooting or a wide range of .300 BLK ammunition. Every CMMG product is backed by a Lifetime Quality Guarantee against material and workmanship defects.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003ePatent-pending Compact Action Direct Impingement system houses the full action and recoil assembly in the upper receiver for a shorter, more compact profile than traditional ARs\u003c\/li\u003e\n  \u003cli\u003e14.5\" 4140CM steel barrel with SBN finish and CMMG ZEROED SVD Brake pinned and welded to a legally compliant 16.1\" overall barrel length -- no SBR required\u003c\/li\u003e\n  \u003cli\u003eAdjustable 0.750\" gas block allows precise tuning for suppressed or subsonic .300 AAC Blackout loads as well as a wide variety of supersonic ammunition\u003c\/li\u003e\n  \u003cli\u003eCMMG 13.5\" proprietary handguard paired with a full-length top Picatinny rail and DISSENT reversible side charging handle for rapid, accurate bolt operation\u003c\/li\u003e\n  \u003cli\u003eArmor Black Cerakote finish over a DISSENT 7075-T6 aluminum upper receiver for superior corrosion resistance, hardness, and lasting durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\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 CMM30B8A6FAB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 810097502499\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 .300 AAC Blackout\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 14.5\"\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, Salt Bath Nitrided (SBN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Device:\u003c\/strong\u003e CMMG ZEROED SVD Brake, Pinned and Welded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Thread:\u003c\/strong\u003e 5\/8 x 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Barrel Length (with brake):\u003c\/strong\u003e 16.1\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Port Location:\u003c\/strong\u003e Carbine\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 13.5\" Proprietary\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCharging Handle:\u003c\/strong\u003e DISSENT Side Charger - Reversible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.0 lbs.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 23.6\"\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.
