The CMMG Resolute MK4 is a modern sporting rifle chambered in 5.7x28mm with a 32-round magazine capacity. It runs on CMMG's Radial Delayed Blowback operating system, which cycles smoothly and keeps felt recoil low — useful for quick follow-up shots.
The barrel is 4140CM steel with a salt bath nitride finish. The CMMG ZEROED muzzle brake reduces muzzle rise during rapid fire. Controls are ambidextrous — the ZEROED ambi charging handle and safety selector work for left- and right-handed shooters. The upper receiver is billet 6061 T6 aluminum; the lower is forged aluminum, keeping weight down without sacrificing strength.
The Resolute MK4 suits intermediate to advanced shooters who want a rifle that handles varied conditions. It works for competitive shooting or home defense.
The 32-round magazine and fast follow-up capability make it a reasonable pick for three-gun competitions. At home, the manageable weight and effective caliber translate to a practical defensive option. It also works for plinking or varmint hunting, where the 5.7x28mm's flat trajectory helps at longer ranges.

The CMMG Resolute MK4 in 5.7x28mm draws a genuine split in feedback.
On the positive side, the 5.7x28mm caliber gets consistent praise for low recoil and high velocity — new and experienced shooters both find it fun to shoot, and the round holds up well in tactical discussions. Ergonomics come up often: the grip and adjustable stock feel balanced, and the platform is generally reported as reliable across different shooting conditions. The 32-round capacity is a real advantage for extended sessions.
The criticisms are mostly practical. 5.7x28mm ammunition costs more and is harder to find than .223 or 9mm, which discourages frequent practice. Some users find the rifle heavier than expected, which matters over long carry distances. Aftermarket support is thinner than on standard AR-15 platforms. And shooters coming from more conventional rifles sometimes need time to adapt to the caliber's handling characteristics.
Overall the conversation reflects genuine enthusiasm for what the platform does differently, alongside honest questions about ammo cost and long-term usability.
