CMMG DISSENT MK4 — 6mm ARC, 10+1 Capacity (Includes 2 Magazines), 16.10" Barrel, Coyote Tan Receiver, 15" M-LOK® Handguard, Side Charging Handle, Black Side-Folding Stock & ZEROED™ Grip, Muzzle Brake, 60/90 Ambi Safety, Adjustable Gas Block | Model 60AA90CCT | UPC 810144721576 Meet the modern do-everything AR that stretches your practical range. The CMMG DISSENT MK4 in 6mm ARC blends a flat-shooting, high-BC cartridge with a 16.10" barrel, a rigid 15" M-LOK® free-float handguard, and a side charging handle for slick, optics-friendly manipulation. Finished in Coyote Tan with a Black side-folding stock and ZEROED™ ergonomic grip, this rifle is tuned for accuracy, fast handling, and real-world configurability—whether you’re ringing steel at 1/2 mile, calling predators, or training hard at the range. Why Choose the DISSENT MK4 in 6mm ARC 6mm ARC chambering — Purpose-built for superior external ballistics from an AR-15 footprint: high ballistic coefficients, flatter trajectory, and excellent wind performance. 16.10" barrel + muzzle brake — Practical length for velocity and balance; brake helps tame muzzle rise for faster follow-ups. 15" free-float M-LOK® handguard — Solid accessory mounting while preserving barrel harmonics for better precision. Side charging handle — Keep your optic/LPVO mounted low and manipulate the action without breaking cheek weld. Black side-folding stock — Transport, storage, and vehicle carry get easier; deploy quickly to shooting length. Coyote Tan receiver — Durable, low-glare finish that looks as tough as it runs. ZEROED™ pistol grip — Modern angle and texture for consistent trigger access and recoil management. 60/90 ambidextrous safety — Choose the throw you prefer; mirrored control for strong- or support-side use. Adjustable gas block — Tune for ammo, suppressors, and conditions to maintain reliable, smooth cycling. 10+1 capacity & (2) magazines included — Range-ready out of the box (capacity and mag type may vary by jurisdiction). 6mm ARC: Reach Farther with Less Guesswork Developed around high-BC 6mm bullets, 6mm ARC maintains velocity and fights wind better than typical .22-cal AR loads—without jumping to a large-frame rifle. Expect flatter trajectory, reduced drift, and excellent retained energy for practical long-range and field work. It’s an ideal match for the DISSENT’s free-float precision architecture and adjustable gas system. Handling & Control, Dialed Side charging keeps manipulations clear of big turrets and magnifiers. Muzzle brake reduces movement so you can spot impacts and correct quickly. Ambi 60/90 safety lets you set familiar 90° throws or faster 60° engagement to taste. Folding stock simplifies transport, rucks, and trunks while preserving a solid cheek weld when locked. Accessorize Without Compromise The 15" M-LOK® handguard offers generous rail estate for white lights, bipods, QD sling cups, hand stops, and pressure pads—without interfering with barrel harmonics. A continuous top rail makes mounting LPVOs (1–6×/1–8×/1–10×) or dot + magnifier combinations straightforward. Ideal Use Cases Predator & varmint — Fast, flat, and wind-savvy with quality 6mm loads. Steel & practical rifle — Consistent tracking and easy dope for extended-range drills. Backcountry/ranch rifle — Durable finish, folding stock, and smooth cycling for real-world carry. Suppressor-curious — Adjustable gas block helps tailor impulse (where suppressors are legal). Setup Tips for Best Performance Optic pairing: A 1–10× LPVO or 3–18× precision scope complements 6mm ARC’s reach; consider a 20 MOA base if you’ll dial past mid-range. Zero strategy: 100-yard zero is common for data-driven dialing; verify holds out to your typical max distance. Gas tuning: Start per CMMG guidance, then fine-tune the adjustable gas block for your load and any muzzle device/suppressor. Data card: Build dope for your preferred 103–108gr high-BC loads; note environmental shifts and any POI change with/without suppressor. Safety, Compliance & Care Know the laws in your area regarding magazine capacity, features, and suppressor ownership. Maintenance: Keep the BCG and charging surfaces lightly lubricated; check handguard, optic mounts, and muzzle device after the first heat cycles. Ammo: Use quality 6mm ARC from reputable makers; confirm function and zero before field use.
