Precision, portability, and modern ergonomics—now in a flat-shooting .22 ARC package. The CMMG DISSENT® Mk4 22 ARC with a 16.1" barrel brings the DISSENT’s signature compact, bufferless feel to a full-length rifle that still carries light, balances well, and stays remarkably stable on target. Finished in Sniper Grey (SNGRY) for low-glare style, this configuration—Model 28A490FSG, UPC 810148627225—is built for shooters who want long-range consistency, a forgiving recoil impulse, and AR modularity for optics, triggers, and accessories.

Why Choose the DISSENT Mk4 in .22 ARC

• Efficient, flat ballistics: The .22 ARC cartridge is engineered for high-BC projectiles that hold velocity and resist wind, simplifying holds at practical long-range distances.

• Bufferless DISSENT architecture: Enjoy a shorter overall footprint and smoother handling while retaining the velocity benefits of a 16.1" barrel.

• Mk4 AR compatibility: Leverage a broad ecosystem of AR-pattern accessories—optics, mounts, triggers, grips, and sling hardware—to tailor your rifle to the mission.

• Sniper Grey finish: Durable, modern coating that looks professional and reduces visual signature in the field.

• Confidence under recoil: Manageable impulse and fast sight recovery help you spot impacts and send accurate follow-ups.

Performance Benefits You’ll Notice

• Flatter trajectories & less wind drift: The .22 ARC’s modern bullets deliver predictable dope from near-to-far targets.

Ideal Use Cases

• Predator & varmint: Build a lightweight calling rig; capitalize on flat flight paths for ethical hits (where legal).

• Practical carbine/DMR training: Stretch to distance, refine wind calls, and develop position work without punishing recoil.

• Range accuracy work: Ring steel confidently, track impacts, and refine holdovers.

Setup Ideas

• Optics: 1–10× LPVO for do-everything versatility, or a 2–12× / 3–15× for precise dialing and hold mapping.

• Support: Compact bipod or tripod clamp for prone and glassing-stand shots.
