Description
Picture this: you need a rifle that bridges the gap between a lightweight AR-15 and a hard-hitting brush gun, something that’s at home in a deer stand one minute and on a practical range the next. That’s the exact scenario the CMMG Resolute 300 MK4 .350 Legend, 16.1″ Barrel, RipStock, Midnight Bronze, 10rd is built for. It’s a purpose-built modern sporting rifle chambered in the potent .350 Legend cartridge, designed for hunters and shooters who demand a reliable, accurate, and versatile platform that delivers significant energy downrange without punishing recoil.
This isn’t just another black rifle. The CMMG Resolute 300 MK4 starts with a robust 16.1-inch barrel, the optimal length for balancing velocity and maneuverability in thick cover. The .350 Legend cartridge itself is the key—it generates impressive terminal ballistics for medium game, stays supersonic past 200 yards for flat trajectories, and maintains compatibility with standard AR-15 magazines and bolts, a huge practical advantage. The distinctive Midnight Bronze Cerakote finish isn’t just for looks; it provides a durable, corrosion-resistant shield against the elements, whether you’re facing a Missouri drizzle or brushing through dew-covered timber.
Let’s talk about the RipStock. This isn’t a standard M4 stock. CMMG’s design incorporates an aggressive texturing pattern on the cheek weld and a deeply checkered rubber buttpad. The result? A rock-solid anchor point that stays put during rapid strings of fire or when you’re lining up a vital shot on a moving target. The stock’s adjustment is mil-spec compatible, so you can fine-tune the length of pull to fit you perfectly, whether you’re wearing a t-shirt or layered in winter gear. Here’s the thing—this rifle is drop-in ready. It ships fully assembled and tested, requiring no gunsmithing to get you from the box to the bench. Just perform your standard safety check, and you’re set.

Pros & Cons
The Resolute 300 MK4’s strengths are clear. The .350 Legend offers serious knockdown power for deer and hog hunting, often exceeding the energy of traditional rounds like the .30-30 Winchester. It uses standard AR-15 pattern components, meaning magazines and many accessories are widely available and affordable. The RipStock provides exceptional control, and the 16.1-inch barrel makes the platform handy in blinds or dense woods. On the downside, ammunition for .350 Legend, while growing, isn’t as ubiquitous or cheap as 5.56 NATO. The rifle’s weight of roughly 7.5 pounds is also a bit heavier than a basic 5.56 carbine, a trade-off for the heavier barrel and caliber.

Frequently Asked Questions
Q: Is the .350 Legend a good deer hunting round out of a 16-inch barrel?
A: Absolutely. The .350 Legend is designed to perform optimally from shorter barrels, maintaining excellent velocity and energy. From a 16-inch barrel, it reliably delivers more than enough foot-pounds of energy for ethical whitetail harvests within typical hunting ranges, making it a fantastic choice for hunters in wooded or broken terrain.
Q: What magazines does this rifle use?
A: The CMMG Resolute 300 MK4 is designed to work with standard AR-15 .350 Legend magazines. Many manufacturers like CMMG, Magpul, and Lancer Systems produce reliable options. The included 10-round magazine is ideal for hunting compliance, but higher-capacity range magazines are readily available.
Q: Can I use my existing AR-15 lower receiver with this upper?
A: Yes, in most cases. The CMMG Resolute 300 MK4 upper receiver is built to mil-spec dimensions and should mate correctly with a standard AR-15 lower. Remember, FFL transfer required for firearm purchases of complete rifles or lowers. This upper is available at firearms-missouri.com for Missouri residents and nationwide.
