Whether you are a seasoned firearms enthusiast looking to expand your collection, a new shooter desiring a user-friendly and effective home defense solution, or a competitive shooter aiming for an edge in PCC divisions, this robust carbine offers a compelling suite of features. The CMMG Resolute 300 MK17, identified by its unique SKU 92AE68F-OD and UPC 810050559385, is engineered to address the core challenges faced by conventional blowback PCCs, delivering a shooting experience that is both smooth and highly reliable.

The CMMG Resolute 300 MK17: A Deep Dive into Innovation

What makes the CMMG Resolute 300 MK17 a standout option in the crowded PCC market? Its design philosophy centers on superior ergonomics, remarkable reliability, and a groundbreaking operating system that sets it apart.

The Revolutionary Radial Delayed Blowback System

At the heart of the CMMG Resolute 300 MK17's superior performance is CMMG's patented Radial Delayed Blowback operating system. Unlike traditional direct blowback systems commonly found in many 9mm PCCs, which rely on a heavy bolt and spring to absorb recoil, Radial Delayed Blowback ingeniously redirects some of the expanding gas to lightly push the bolt group back against the bolt carrier. This momentary delay in the bolt's unlocking allows chamber pressure to drop before the bolt begins its rearward travel, resulting in a significantly softer and smoother recoil impulse. For shooters, this translates directly into faster follow-up shots, reduced muzzle rise, and a more comfortable shooting experience, especially during extended range sessions. This innovative system also contributes to a cleaner operating firearm, as less gas is vented directly back into the receiver compared to many other designs, meaning less fouling and easier maintenance.

The MK17 Platform: Unrivaled Magazine Compatibility

One of the most practical and user-friendly aspects of the CMMG Resolute 300 MK17 is its native compatibility with ubiquitous Glock® pattern magazines. The 'MK17' designation specifically refers to CMMG's lower receiver design tailored for these readily available and highly reliable magazines. This eliminates the need for proprietary and often expensive magazines, making it incredibly convenient for users who already own Glock pistols or prefer to standardize their ammunition and magazine supply. The CMMG Resolute 300 MK17 is supplied with a 21-round magazine, providing ample capacity for both defensive and recreational purposes, allowing for extended shooting without frequent reloads.

Optimal Barrel Length and Caliber Versatility

Equipped with a 16.10-inch barrel, the CMMG Resolute 300 MK17 meets the legal requirements for a rifle, avoiding the complexities associated with Short Barreled Rifles (SBRs), while still maintaining excellent maneuverability. The 9mm Luger (9x19mm Parabellum) chambering offers a host of advantages. It is one of the most widely available and affordable pistol calibers, making training and plinking more economical. Furthermore, modern 9mm ammunition, particularly hollow-point designs, offers effective terminal ballistics for personal and home defense scenarios, delivering a potent yet controllable solution. The carbine’s threaded barrel also allows for easy attachment of muzzle devices, including suppressors, further enhancing its versatility and reducing noise pollution at the range.

Durable and Distinctive OD Green Cerakote Finish

Beyond its internal engineering, the CMMG Resolute 300 MK17 features a striking OD Green Cerakote finish on its receiver. Cerakote is a polymer-ceramic composite coating known for its exceptional durability, corrosion resistance, and abrasion resistance. This not only gives the carbine a distinctive and appealing aesthetic but also provides a robust layer of protection against the elements, wear, and tear, ensuring that the firearm maintains its pristine appearance and functional integrity even after years of rigorous use. The OD Green hue offers a tactical appeal and blends well into various outdoor environments, making it a favorite among those who appreciate both form and function.

The Ergonomic CMMG RipStock

The CMMG Resolute 300 MK17 comes standard with the CMMG 6 Position RipStock. This innovative stock system is designed for rapid deployment and adjustment, allowing shooters to quickly customize the length of pull to suit their body mechanics, shooting stance, and layering of tactical gear. The RipStock is known for its smooth operation and solid lock-up, providing a stable shooting platform that enhances accuracy and control. Its design also contributes to the carbine's overall compact footprint when collapsed, making it easier to store and transport discreetly. The combination of its rapid adjustment and secure lock-up enhances the carbine's adaptability in dynamic shooting situations.

Uncompromising Build Quality and CMMG Heritage

CMMG has established itself as a leader in the firearms industry, particularly renowned for its innovation in AR platform rifles and pistol caliber carbines.
