## Description

The CMMG Resolute 200 is a semi-automatic AR-platform rifle chambered in 5.7x28mm. The 5.7x28mm cartridge produces a flat trajectory and low recoil compared to typical pistol-caliber carbine rounds, and the 40-round magazine means fewer reloads during range sessions. At 16.1 inches of barrel and a 1:9 twist rate, it's set up for the velocity the cartridge needs.

The CMMG RipStock is the collapsible stock included on the Resolute 200. It adjusts for length of pull and locks solidly at each position. Polymer grip and stock keep weight down. The 5.7x28mm chambering is uncommon in AR-pattern rifles; CMMG's implementation uses a modified bolt and barrel to handle the cartridge's geometry without exotic components.

## What Customers Say

*AI-generated insights from customer reviews*

The Resolute 200 attracts shooters who want something other than the usual 5.56 or 9mm in an AR chassis. The 5.7x28mm generates genuine interest. People like the combination of low recoil, high velocity, and the 40-round magazine capacity. Most owners report good accuracy and manageable handling.

Common positives: the recoil is light enough that new shooters adapt quickly, the 40-round capacity extends range sessions, and the rifle is compatible with standard AR accessories for optics and rails. Build quality gets generally good marks.

Ammo availability is the recurring concern. 5.7x28mm is less stocked than 5.56 or common pistol calibers, and it costs more per round. Availability tightens during high-demand periods. Some users also note that reliability varies slightly with different ammunition brands, so finding the right load takes some testing.

Price relative to comparable 5.56 ARs comes up, and some buyers wonder whether the 5.7x28mm's practical advantages over standard calibers justify the premium. For shooters specifically seeking the cartridge, the Resolute 200 is one of the few AR-pattern options available, which limits direct comparison shopping.
