22-250 Semi Auto Rifle Magazine Compatibility
An important distinction of the CM10 22-250 Semi Auto Rifle is its dedicated magazine requirement.
The 22-250 Remington has a shorter cartridge overall length than cartridges traditionally associated with the LR/SR magazine pattern. Chattahoochee Munitions supplies a purpose-modified magazine for this configuration.
The included 10-round magazine begins as an Amend2 Mod-2 AR10/SR25 polymer magazine and is modified and refinished by Chattahoochee Munitions for 22-250 Remington.
The completed magazine has a modified follower and fitted internal components specific to the cartridge. It is distinct from the factory Magpul magazine used in the CM10 22 Creedmoor, 6mm Creedmoor, and 243 Winchester configurations.
Additional information is available on the 22-250 Magazine product page.
22-250 Semi Auto Rifle Suppressor Considerations
For its supersonic CM10 platforms, Chattahoochee Munitions generally recommends a flow-through or low-back-pressure suppressor.
Suppressor backpressure can influence the operating characteristics of 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.
