The CMMG Resolute Mk4 6mm ARC Rifle: Precision, Performance, and Versatility for the Modern Shooter
For discerning shooters seeking an advanced sporting rifle that blends compact maneuverability with long-range ballistic prowess, the CMMG Resolute Mk4 chambered in 6mm ARC stands as a formidable solution. This rifle, specifically the 60A10B5TI model, is meticulously engineered to provide exceptional performance across a spectrum of shooting disciplines, from precision target shooting to effective hunting in diverse environments. If you’ve ever asked, "What's the best AR-platform rifle for extended range performance without the bulk of an AR-10?" or "Can an AR-15 effectively reach out to 1000 yards?", the CMMG Resolute Mk4 in 6mm ARC offers a compelling answer. Available at DEGuns, this rifle represents the pinnacle of CMMG's commitment to innovation and quality.
Unleashing the Power of 6mm ARC: A Cartridge Redefined
Introduced in 2020 by Hornady, the 6mm ARC (Advanced Rifle Cartridge) was a game-changer, specifically designed to maximize ballistic performance within the popular AR-15 platform. This innovative round addresses the long-standing desire for an AR-15 compatible cartridge that can rival the extended-range capabilities typically associated with larger, heavier AR-10/LR308 style rifles. The 6mm ARC achieves this by optimizing bullet design and case capacity to deliver superior aerodynamics and energy retention downrange.
Why Choose 6mm ARC Over Other Calibers?
The decision to opt for a 6mm ARC rifle like the CMMG Resolute Mk4 often comes down to its unique blend of attributes:
- Exceptional Ballistics: The 6mm ARC is renowned for its high ballistic coefficient (BC) bullets, which translate to flatter trajectories, less wind drift, and excellent energy delivery at extended distances. This means more predictable performance and greater accuracy, particularly beyond 300 yards.
- AR-15 Compatibility: Unlike cartridges that require a larger AR-10 receiver, the 6mm ARC operates seamlessly within the standard AR-15 footprint. This allows for lighter, more maneuverable rifles that benefit from the vast aftermarket support and familiarity of the AR-15 platform.
- Reduced Recoil: Compared to larger long-range cartridges like the .308 Winchester, the 6mm ARC offers significantly reduced recoil, making it more comfortable to shoot for extended periods and allowing for faster follow-up shots. This is a significant advantage for competitive shooters and hunters who value quick recovery and shot placement.
- Versatile Applications: Whether your passion lies in punching paper at long distances, ringing steel in precision rifle competitions, or ethically taking down medium-sized game like deer and hogs, the 6mm ARC proves itself highly capable. Its flat-shooting nature minimizes holdover calculations, simplifying shot placement.
The CMMG Resolute Mk4 6mm ARC is not just a rifle; it's a strategic tool for shooters who demand precision and reach from a lightweight, agile platform.
CMMG Resolute Mk4: Designed for Excellence
The CMMG Resolute series is built on a philosophy of delivering peak performance in a carbine-length package, bridging the gap between overly cumbersome full-size rifles and the ballistic limitations of pistols or SBRs at longer ranges. The Mk4 variant, optimized for the 6mm ARC, exemplifies this philosophy. It's the rifle that's "never out of place," equally at home on the range, in the field, or in a competitive shooting scenario.
Key Design and Ergonomic Enhancements
Every component of the CMMG Resolute Mk4 6mm ARC is chosen and integrated to enhance the user experience and maximize performance:
- CMMG ZEROED Parts and Accessories: This rifle comes fully equipped with CMMG's suite of ZEROED parts, a testament to their commitment to offering a complete, high-performance package right out of the box. These include the CMMG Zeroed Muzzle Brake, which effectively mitigates recoil and muzzle rise, enhancing control and allowing for quicker target re-acquisition. The ambidextrous lever safety is another key ZEROED component, providing intuitive and reliable operation for both right and left-handed shooters, a crucial feature for dynamic shooting situations.
- The Legendary CMMG RIPSTOCK: A standout feature, the CMMG 6 Position RipStock is renowned for its rapid deployment and robust construction. Unlike traditional buttstocks, the RIPSTOCK allows for quick, positive engagement without snagging, ensuring you can get on target swiftly and efficiently. Its six-position adjustability ensures a comfortable and stable shooting platform for shooters of various sizes and in different shooting positions.
- EML 15 Handguard: Modern Aesthetics and Functionality: The CMMG EML 15 handguard is not just visually striking with its sleek profile; it's also highly functional. It features M-LOK attachment slots at the 3, 6, 9, and even the 12 o'clock positions. This innovative design offers ample space for mounting essential accessories like lights, lasers, bipods, and foregrips, while simultaneously reducing overall weight by omitting a full-length Picatinny rail section on top. This thoughtful design contributes to the rifle's light and agile feel (weighing only 6.40 lbs).
- Titanium Cerakote Finish: The receiver and handguard boast a durable Titanium Cerakote finish. Beyond its striking aesthetic appeal, Cerakote is celebrated for its exceptional resistance to corrosion, abrasion, and chemicals. This protective layer ensures the rifle maintains its pristine appearance and structural integrity even under harsh environmental conditions and rigorous use, contributing to its longevity and reliability.
Precision Engineering: The Core of the Mk4's Performance
The internal mechanics and materials selection of the CMMG Resolute Mk4 are where its true precision and reliability shine.
Barrel: The Heart of Accuracy
The 16.10-inch barrel is crafted from Chrome Moly Steel, a material known for its strength and resistance to wear. It features a Black Nitride finish, which provides superior corrosion resistance and increased surface hardness compared to traditional phosphate coatings, leading to a longer barrel life and easier cleaning. The barrel is threaded (5/8"x24) for easy installation of the included CMMG Zeroed Muzzle Brake or other muzzle devices, including suppressors. With a 1:7.50" twist rate, this barrel is specifically optimized to stabilize a wide range of popular 6mm ARC bullet weights, ensuring exceptional accuracy and consistent performance across various ammunition types.
Direct Impingement Operating System
The CMMG Resolute Mk4 utilizes a direct impingement operating system, a tried-and-true method for AR-platform rifles. This system is known for its simplicity, lightweight nature, and inherent accuracy, as it minimizes moving parts and keeps the bore aligned directly with the gas system. This reliable operation contributes to the rifle's consistent performance shot after shot.
Receiver and Trigger System
The receiver is constructed from durable aluminum, providing a robust yet lightweight foundation for the rifle. The presence of a Picatinny rail on the upper receiver ensures seamless integration of optics, iron sights, or other sighting systems. The single-stage trigger offers a clean and crisp break, promoting precision and consistent shot placement, which is vital for long-range accuracy and competitive shooting. The black polymer grip provides a comfortable and secure hold, enhancing control and shooter comfort during extended sessions.
Optimized for the User: Real-World Applications
The CMMG Resolute Mk4 6mm ARC is more than just a collection of high-quality parts; it's a complete system designed to excel in real-world scenarios.
Hunting with the CMMG Resolute Mk4
For hunters, the 6mm ARC's ballistic performance in an AR-15 platform offers significant advantages. The flat trajectory and excellent energy retention make it an ideal choice for medium-sized game, such as deer, hogs, and varmints. The rifle's manageable weight (6.40 lbs) and overall length (32.50") make it easy to maneuver through dense brush or carry for extended periods in the field. The CMMG Zeroed Muzzle Brake helps manage recoil, allowing hunters to quickly re-acquire targets for follow-up shots if necessary, while the Titanium Cerakote finish provides added durability against the elements.
Long-Range Target and Competition Shooting
Precision shooters will appreciate the inherent accuracy provided by the 6mm ARC's design, the 1:7.50" barrel twist, and the single-stage trigger. The predictable performance of the 6mm ARC minimizes external variables, allowing shooters to focus on fundamental marksmanship. The CMMG RipStock ensures a stable shooting platform, while the M-LOK handguard provides ample space for bipods and other accessories essential for long-range disciplines. The CMMG Resolute Mk4 is a strong contender for those looking to compete in AR-15 division matches or simply enjoy pushing their limits at extended ranges.
General Sporting and Recreational Use
Even for general recreational shooting, the CMMG Resolute Mk4 offers an incredibly satisfying experience. Its ergonomic design, combined with the mild recoil of the 6mm ARC, makes it enjoyable to shoot for hours. The capacity of 10+1 rounds (with AR-15 style magazines) is suitable for various range activities, and the rifle's overall reliability makes it a trusted companion for any shooting enthusiast.
