CMMG Resolute Mk4 6mm ARC: Unleashing Precision and Power in an AR-15 Platform

Are you an avid hunter seeking reliable, long-range performance for medium game? Do you compete in precision shooting sports and demand predictable ballistics from a compact rifle? Or perhaps you’re an AR-15 enthusiast looking to bridge the gap between the compact maneuverability of your favorite platform and the extended range capabilities typically reserved for larger, heavier rifles? If these questions resonate with you, the CMMG Resolute Mk4 chambered in 6mm ARC is engineered precisely for your needs.

This advanced carbine is designed to solve a fundamental challenge: delivering superior ballistic performance and long-range accuracy within the familiar, modular AR-15 framework. Gone are the days when extended-range precision meant sacrificing portability or dealing with the bulk of an AR-10/LR-308 style rifle. The CMMG Resolute Mk4 offers a compelling solution, striking a perfect balance of size, power, and precision.

The Revolutionary 6mm ARC (Advanced Rifle Cartridge)

At the heart of the CMMG Resolute Mk4’s extraordinary capabilities is the 6mm ARC. Introduced in 2020, this innovative cartridge was meticulously developed by Hornady to provide exceptional ballistic performance from an AR-15 platform. It was engineered from the ground up to maximize the potential of the standard AR-15 bolt face, delivering efficiency and power previously unseen in this form factor.

Why is the 6mm ARC a game-changer?

• Superior Ballistics: The 6mm ARC excels in external ballistics, boasting a flatter trajectory and significantly reduced wind drift compared to common AR-15 cartridges like 5.56 NATO. This translates to fewer holdovers and easier corrections, making hits at extended ranges much more attainable.
• Extended Range Performance: While still fitting within the AR-15 magazine well, the 6mm ARC can rival the extended-range performance of larger rounds like the .308 Winchester, often used in AR-10 platforms. This allows shooters to confidently engage targets out to 1000 yards or beyond with the right ammunition and shooter skill.
• Optimized for AR-15: Unlike wildcat cartridges or adaptations, the 6mm ARC was specifically designed around the AR-15 architecture, ensuring optimal feeding, extraction, and overall reliability.
• Versatility: Its balance of speed and projectile weight makes it an excellent choice for a variety of applications, including hunting deer, hogs, and varmints, as well as competitive precision shooting and long-range target practice. It provides potent energy on target without excessive recoil, allowing for faster follow-up shots and extended shooting sessions.

For shooters who demand more reach and impact than traditional 5.56/.223 AR-15s can provide, but find AR-10s too large or heavy for their preferences, the 6mm ARC in the CMMG Resolute Mk4 offers the perfect middle ground. It's the predictable, flat-shooting round that makes a great choice for discerning hunters and target shooters alike.

The CMMG Resolute Mk4 Platform: Engineered for Excellence

The CMMG Resolute Mk4 is not just a rifle; it's a meticulously crafted system designed for peak performance and user comfort. Every component, from its durable finish to its specialized stock, contributes to its reputation as a rifle that is "never out of place."

Key Features and Design Philosophy:

• Optimal Carbine Length (16.10"): At 16.10 inches, the barrel length strikes an ideal balance between ballistic efficiency for the 6mm ARC and maneuverability. This carbine length makes the Resolute Mk4 easy to handle in varied environments, from dense woods to shooting benches, while still allowing the 6mm ARC to achieve impressive velocities. Its overall length of 32.50 inches further contributes to its compact, yet capable, profile.
• Robust Construction: The receiver is crafted from high-quality aluminum, providing a lightweight yet incredibly durable foundation for the rifle. The Charcoal Green Cerakote finish on the receiver and handguard isn't just aesthetically striking; it offers superior abrasion resistance, corrosion protection, and chemical resistance, ensuring the rifle stands up to the harshest conditions.
• Black Nitride Barrel: The 16.10-inch barrel, made from durable Chrome Moly Steel, features a Black Nitride finish. This advanced treatment provides exceptional hardness, corrosion resistance, and lubricity, leading to increased barrel life, easier cleaning, and consistent accuracy. The 1:7.5-inch twist rate is precisely matched to stabilize the projectiles commonly used in 6mm ARC, ensuring outstanding precision at all ranges.
• CMMG ZEROED Muzzle Brake: The barrel is expertly threaded with a 5/8"x24 pattern and fitted with a CMMG Zeroed Muzzle Brake. This effectively reduces recoil and muzzle rise, allowing shooters to maintain their sight picture and make faster, more accurate follow-up shots. The threading also provides versatility for attaching suppressors or other muzzle devices.
• CMMG 6-Position RipStock: One of CMMG's most innovative features, the RipStock allows for quick, tool-free adjustment to six different positions. This rapid deployment and stowage capability makes the Resolute incredibly adaptable, whether you're adjusting for different shooting positions, body types, or storage requirements. Its synthetic material ensures durability and lightweight performance.
• CMMG EML 15 Handguard with M-LOK: The new EML 15 handguard elevates both style and functionality. It features M-LOK attachment slots at the 3, 6, 9, and 12 o'clock positions. This design strategically reduces weight by omitting a full-length Picatinny section on top, while still providing ample space for mounting essential accessories like lights, lasers, bipods, and foregrips. The slim profile of the M-LOK handguard also offers improved ergonomics and a comfortable grip.
• Direct Impingement Operating System: Employing the proven direct impingement system, the Resolute Mk4 offers reliable operation, simplicity, and a lightweight design.
• Enhanced Ergonomics: The rifle features a comfortable Black Polymer grip, designed to provide a secure and positive hold, enhancing control and reducing shooter fatigue.
• Ambidextrous Safety: The inclusion of an ambidextrous lever safety ensures that the rifle is equally comfortable and safe to operate for both right and left-handed shooters, a crucial detail for maximum user accessibility.
• Single-Stage Trigger: The single-stage trigger provides a crisp, predictable break, essential for precision shooting. This consistency allows shooters to concentrate on their fundamentals without anticipating a varying trigger pull.
• 10+1 Capacity: With a 10-round magazine capacity (plus one in the chamber), the CMMG Resolute Mk4 adheres to various regional regulations while still offering ample firepower for hunting or target shooting scenarios. It utilizes readily available AR-15 type magazines, ensuring compatibility and ease of acquisition.
• Lightweight Design: Weighing in at just 6.40 lbs, the CMMG Resolute Mk4 is remarkably light for its capabilities, making it comfortable to carry on long hunts or during extended range sessions.
