22-250 AR — Dedicated Magazine Compatibility
The CM10 22-250 Remington uses a dedicated 10-round magazine rather than the factory Magpul PMAG supplied with other Predator Plains CM10 chamberings.
The shorter cartridge overall length of 22-250 Remington creates different magazine requirements within the large-frame semi-automatic platform.
Chattahoochee Munitions supplies a modified Amend2 Mod-2 AR10/SR25 magazine for this configuration. The magazine uses a modified follower and fitted internal components specific to the cartridge.
Each completed magazine is surface-prepared and refinished in Black or Coyote Cerakote.
Learn more about the dedicated 22-250 Magazine, including its specifications and compatibility.
22-250 AR — Suppressor Considerations
For supersonic CM10 platforms, Chattahoochee Munitions generally recommends a flow-through or low-back-pressure suppressor.
Suppressor backpressure can influence operating-system characteristics in gas-operated semi-automatic firearms. The CM10 includes a Superlative Arms adjustable gas block and Odin Adjustable Buffer as part of its operating system.
Suppressor compatibility must be confirmed against the manufacturer’s cartridge ratings, barrel-length restrictions, bore specifications, and mounting requirements.
Supersonic projectiles continue to produce a ballistic shock wave even when a suppressor is used. Appropriate hearing protection remains recommended.
