CM7S 22 ARC Bolt Actions

Chattahoochee Munitions manufactures the CM7S 22 ARC bolt action as complete factory firearms and barreled actions. The complete firearms come as a 12.5-inch pistol or SBR at 6 lb 6 oz and an 18-inch rifle at 7 lb 7 oz, each in Black Tungsten, Cobalt Kinetics Green or FDE Metallic Cerakote. Every CM7S 22 ARC uses a Mos-Tek 416R stainless barrel with a 1:8 twist in E100 Blackout Cerakote, a Remington 700-footprint action, a CM7 billet aluminum chassis and a TriggerTech Remington 700 Primary trigger.

The 1:8 twist stabilizes long 88-grain .224 bullets. Because the CM7S is manually operated and does not use gas to cycle, Chattahoochee Munitions recommends an enclosed suppressor. See the full lineup in Flight Deck 22, and compare the CM7S with the CM15 in the 22 ARC rifle guide.

A 10-round short-action AICS-pattern 22 ARC magazine. It is not interchangeable with the CM15’s AR15-pattern magazine.
