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.
