CMMG DISSENT MK4 — .300 Blackout, 16.1" Barrel, Semi-Auto Rifle, Midnight Bronze Cerakote® | Model 30A750A-MB / 30A750AMB | UPC 810144721491 Meet the do-more blackout carbine. The CMMG DISSENT MK4 (.300 BLK) in Midnight Bronze Cerakote® combines a handy 16.1" barrel, a rigid free-float M-LOK® handguard, and AR-familiar controls to deliver a soft-shooting, suppressor-friendly platform that shines from woods to range. Whether you’re optimizing for subsonic quiet or supersonic punch, the DISSENT MK4 brings reliability, accuracy, and easy accessorizing in a tough, low-glare finish. Why Choose the DISSENT MK4 in .300 BLK .300 Blackout chambering — Run subsonic for low blast/signature (ideal for suppressed use where legal) or supersonic for added reach and energy. 16.1" barrel — Legal, velocity-friendly length with excellent handling; easy to tune with your preferred muzzle device or suppressor mount. Free-float M-LOK® handguard — Solid accessory mounting that preserves barrel harmonics for better practical accuracy. Midnight Bronze Cerakote® — Durable, abrasion- and corrosion-resistant finish that looks as good as it performs. AR-pattern ergonomics — Familiar controls, ready for ambi upgrades; fast learning curve and intuitive manipulation. Optic-ready — Top Pic rail for LPVOs, red dots, or dot+magnifier setups. Built for Practical Precision The DISSENT MK4’s free-float rail keeps pressure off the barrel so your zero stays put when you load barricades, add a bipod, or clamp a hand stop. Pair it with an LPVO (1–6×/1–8×) for do-everything versatility or a red dot + 3× magnifier for speed with mid-range reach. M-LOK slots give flexible mounting for white lights, QD sling cups, bipods, or pressure pads without crowding your grip. .300 BLK Versatility: One Rifle, Two Personalities Subsonic (with appropriate barrel twist and ammo): exceptionally quiet with a suppressor, minimal gas blast, and smooth recoil for fast follow-ups. Supersonic: flatter trajectory and increased energy for general purpose range work and field use. Switching loads is as simple as swapping magazines—no bolt change needed. Handling & Control Balanced 16.1" profile stays lively in tight spaces and blind/stand setups. Muzzle device ready: choose a flash hider, brake, or suppressor mount to tailor recoil and signature. QD-friendly handguard and stock interfaces support modern two-point sling techniques for stability and transitions. Ideal Use Cases Suppressor-friendly builds (where legal) emphasizing subsonic control Range & training carbines with soft recoil and broad ammo options Woods/brush roles where compact handling and energy at practical distances matter Home & property defense configurations with appropriate ammo selection Setup Tips for Best Results Optic pairing: LPVO for do-all utility; red dot + magnifier for speed and simplicity. Zero strategy: Common picks are 50/200 for general use or 100 yards if you’ll dial/hold often. Confirm holds for your specific subsonic and supersonic loads. Gas & recoil tuning: If running a suppressor, consider an adjustable gas block or buffer tuning for optimal ejection and cleaner impulse. Data card: Build dope for both subsonic and supersonic loads; note POI shift with and without your suppressor. Safety, Compliance & Care Know your laws: Ownership, suppressors, and magazine capacities vary by jurisdiction. Maintenance: Keep the BCG lightly lubricated; check handguard, muzzle device, and optic fasteners after initial heat cycles. Ammunition: Use quality .300 BLK from reputable makers; confirm function before critical use.
