Engineered with enhanced features from butt to muzzle, this rifle excels in both performance and durability. At its core, the barrel is crafted from 4140 chrome moly steel, ensuring exceptional accuracy and longevity with a salt bath nitride finish for added durability. The threaded muzzle includes a Zeroed muzzle brake, reducing recoil for swift follow-up shots. Each rifle is finished with a robust Cerakote coating, providing superior resistance to the elements. Designed for ambidextrous operation, the Resolute MK4 features CMMG's Zeroed accessories such as an ambidextrous magazine catch, safety selector and charging handle, facilitating effortless one-handed operation. The CMMG handguard integrates M-LOK slots at the 3, 6 and 9 o'clock positions, along with picatinny rail slots at the top front and rear, allowing for versatile accessory attachment including sights, bi-pods, lights and more. To comply with regulations while maintaining maneuverability, this model utilizes a 14.50 inches barrel with a pinned and welded muzzle brake, achieving an overall barrel length of 16.10 inches. This configuration offers the benefits of a shorter package without requiring NFA/SBR classification. The CMMG Resolute MK4 is not just a rifle; it's a testament to precision engineering and quality craftsmanship, making it a preferred choice for discerning shooters seeking top-tier performance and reliability.
