FEATURES:

The CMMG Endeavor MK3 chambered in .308 Winchester is designed for marksmen who prioritize precision and stability in a semi-automatic rifle platform. Built to deliver long-range performance with accuracy-enhancing features, the Endeavor MK3 is a top-tier choice for competitive shooting, hunting, and tactical applications where distance and consistency matter. The rifle is built on CMMG’s robust MK3 platform, which is specifically engineered for large-frame calibers like the .308 Win, offering a well-balanced blend of power, durability, and user-friendly ergonomics.

Equipped with a 20-inch barrel constructed from 416 stainless steel, the Endeavor MK3 provides excellent barrel life and resistance to fouling, along with consistent harmonics and minimal shift in point of impact. The extended barrel length ensures complete powder burn for maximum velocity and tight groupings downrange. The stainless construction also provides corrosion resistance, making the rifle ideal for long shooting sessions in a variety of conditions. This barrel profile is tailored to support accuracy without unnecessary weight, making the rifle steady in prone or supported positions.

This optics-ready platform features a flat-top upper with a full-length Picatinny rail that accommodates magnified scopes or red dot sights, allowing shooters to customize their optic setups depending on mission or shooting requirements. With a platform designed around precision, the Endeavor MK3 also incorporates the CMMG Zeroed Drop-In Trigger, which provides a crisp, clean break with minimal creep and a short reset. This high-quality trigger promotes repeatable accuracy and faster follow-up shots, critical for both long-range precision and quick engagements.

The rifle is outfitted with a Magpul MOE Rifle Stock, which delivers solid cheek weld, integrated sling mounts, and a stable shooting platform. This fixed stock is ideal for long-range applications, providing a consistent length of pull and helping to mitigate recoil over extended shooting sessions. The stock's design supports comfort and control, especially when paired with the rifle’s extended barrel and precision components.

Available at Smoky Mountain Guns and Ammo, also known as SMGA, the CMMG Endeavor MK3 stands out in the .308 Win category as a purpose-driven rifle that prioritizes accuracy and consistency. It shares the rugged design DNA of the CMMG Banshee MK3 but is tailored for distance shooting with premium materials and thoughtful engineering that meets the demands of serious shooters.
