CMMG Resolute
The CMMG Resolute is the full-size rifle companion to the Banshee — a standard AR-pattern rifle chambered in pistol calibers using CMMG's Radial Delayed Blowback system. Where the Banshee is optimized for compact pistol and SBR configurations, the Resolute delivers the same superior cycling in a 16" rifle format for states and shooters where a full-length rifle is preferred.

Resolute vs. Banshee — Choosing Your Configuration
The Resolute and Banshee share CMMG's Radial Delayed Blowback operating system and are available in the same calibers. The key difference is format: the Banshee uses a compact reduced-scale upper and lower in pistol or SBR configuration; the Resolute uses a standard AR-15 pattern lower with a 16" barrel in standard rifle format. Choose the Banshee if compactness and pistol configuration are priorities. Choose the Resolute if you want a standard rifle format, need a 16" barrel for state compliance, or prefer the full-size AR ergonomics for extended shooting sessions.
Radial Delayed Blowback
CMMG's patented Radial Delayed Blowback system delays bolt opening using a rotating bolt head concept, reducing cycling violence compared to standard blowback PCCs. The result is softer cycling, less felt recoil, and cleaner suppressed operation across all calibers — but especially meaningful for higher-pressure pistol calibers like 10mm and .45 ACP where blowback operation is particularly violent. See our Banshee page for a full explanation of the Radial Delayed Blowback system.
Resolute Configurations
Resolute 100 — Entry-level Resolute with standard components. The most affordable full-size CMMG PCC entry point.
Resolute 200 (MkGs) — Mid-tier with enhanced handguard and improved ergonomics over the 100 series.
Resolute 300 (MkGs) — Premium Resolute with the best trigger, handguard, and overall refinements in the lineup.
Caliber Options
The Resolute is available in 9mm, .45 ACP, 10mm Auto, .40 S&W, .22 LR, and 5.7x28mm depending on configuration. The 10mm Resolute is particularly popular for hunters and outdoors use where pistol caliber rifle performance in a hard-hitting cartridge is desirable.
Magazine Compatibility
Magazine compatibility varies by caliber. The 9mm Resolute typically accepts Glock-pattern or CMMG-proprietary magazines depending on configuration. The .45 ACP version accepts Glock 21-pattern magazines. Verify magazine compatibility for your specific Resolute configuration before purchasing spare magazines.
FAQ
What is the difference between the CMMG Resolute and Banshee?
The Resolute is a full-size rifle with a 16" barrel on a standard AR lower. The Banshee is a compact pistol/SBR on a reduced-scale lower. Both use the Radial Delayed Blowback system and are available in the same calibers.
What calibers does the CMMG Resolute come in?
9mm, .45 ACP, 10mm Auto, .40 S&W, .22 LR, and 5.7x28mm depending on configuration.
Is the CMMG Resolute good for suppressed use?
Yes — the Radial Delayed Blowback system runs suppressed more cleanly than blowback competitors. The 16" barrel also provides a longer host for the suppressor, improving cooling and sound reduction compared to shorter pistol configurations.
What magazines does the CMMG Resolute use?
Varies by caliber. The 9mm typically accepts Glock-pattern magazines. Verify compatibility for your specific configuration.
