The CMMG Dissent Mk4 300 Blackout 30-round pistol magazine is purpose-built for modern short-barreled rifle platforms and pistol-format AR-15 uppers chambered in 300 Blackout. Developed by CMMG—a manufacturer with deep roots in the suppressed and subsonic ammunition community—this magazine serves operators, precision shooters, and law enforcement professionals who depend on reliable ammunition storage in compact, high-round-count formats. The 30-round capacity delivers substantial firepower in a package optimized for tactical environments where magazine changes must be minimized and reload speed maximized.
Construction centers on CMMG's proven metallurgy and witness-hole design, allowing shooters to verify round count at a glance without removing the magazine from a pouch or platform. The titanium components referenced in the model designation (30A0E33-TI) enhance durability and reduce overall weight to 1 pound, a critical advantage in extended operations or when carrying multiple loaded magazines. The feed geometry is engineered specifically for 300 Blackout's larger, shorter cartridge profile, preventing misfeeds and ensuring reliable chambering across bolt-face tolerances. Double-stack, single-feed configuration maximizes capacity while maintaining shallow profile for seamless insertion into magwells.
This magazine is ideal for operators running 300 Blackout pistol-length ARs, short-barreled rifles (SBRs), and dedicated pistol uppers where subsonic or supersonic ammunition demands precise feeding reliability. Law enforcement tactical teams and civilian shooters pursuing suppressed carbine platforms will find the 30-round capacity essential for home defense, precision work, or range training without frequent reloading. CMMG 300 Blackout magazines are forward-compatible across most modern AR-15 lower receivers and upper assemblies chambered in this caliber; always verify your specific platform before purchase. Inspect feed lips and witness holes periodically to maintain optimal performance in field conditions.
