Design and Ergonomics
Built on a proven Cmmg platform, the MK-3 is fitted with a Magpul ACS stock that offers solid cheek weld and tool-less length-of-pull adjustment—important for fast transitions and consistent sighting. The standard safety and an extended latch charging handle make manipulation under stress or while wearing gloves faster and more reliable. At a listed price of $1,599.99 for this Certified Used example, the MK-3 provides compelling value given the included accessories.
Barrel, Accuracy, and Handling
Fluted 1/10 Twist Barrel
The fluted barrel reduces weight and increases surface area for cooling, while the 1/10 twist rate is tuned for stabilizing a wide range of projectiles. The presence of a muzzle device helps manage recoil and muzzle flash, improving follow-up shot control. These features together make the MK-3 capable of practical defensive accuracy and reliable function in extended use.
Modularity and Accessory Support
The 12″ Picatinny quad rail handguard provides abundant real estate for lights, lasers, grips, and backup sights. Because the handguard is full-length, operators can mount accessories according to mission needs without sacrificing barrel profile or balance. The package includes five 20‑round magazines, which adds immediate readiness out of the box.
Certified Used Value
Choosing a Certified Used firearm means the CMMG MK-3 you receive is inspected to “very good to excellent” standards and backed by a no-questions-asked return policy. For shooters who prioritize proven reliability and cost-effectiveness, this Certified Used MK-3 at $1,599.99 is an attractive option. View product details and pricing.
