CM7S 6mm ARC Pistol — 12.5-Inch FDE Metallic
The 6mm ARC pistol from Chattahoochee Munitions combines the CM7S bolt action, a 12.5-inch barrel and CM7 billet-aluminum chassis. This listing offers pistol and SBR configurations within Overwatch 6, CM’s supersonic precision and predator-hunting family.
FDE Metallic Cerakote finishes the chassis and rear components. An AI Dark Earth grip and magazine complement the finish. Both configurations include a TriggerTech Remington 700 Primary trigger and an adjustable cheek riser.
Choose Your 6mm ARC Pistol or SBR Configuration
The selected product option determines the supplied rear configuration:
- Pistol: Telescoping Tailhook brace with adjustable cheek riser.
- SBR: Telescoping buttpad with adjustable cheek riser.
The 12.5-inch barrel, CM7S action and FDE Metallic chassis are shared features. Review your selected option before ordering.
CM7S Action — Full PVD Coating
The CM7S action is designed to Chattahoochee Munitions specifications and uses a Remington 700 footprint. Three locking lugs provide a 60-degree bolt throw. The recoil lug is integrated into the action, and a pinned 20 MOA Picatinny rail provides the optics-mounting interface.
The one-piece bolt features spiral fluting, a .718-inch body diameter, an M16-style extractor and an oversized bolt knob. Wire EDM raceways, a side bolt-stop release and tool-less fire-control removal are additional action features.
A .062-inch firing pin accommodates small-rifle-primer brass. Full PVD coating provides the protective action finish on this 6mm ARC pistol.
Barrel Manufactured in Collaboration with MosTek
The 12.5-inch barrel is manufactured in collaboration with MosTek. It uses 416R stainless steel, 5R rifling and a confirmed 1:7 twist.
A shouldered crown and 5/8×24 muzzle threads complete the barrel specifications. The barrel mounts with a Remage barrel nut and has an E100 Blackout Cerakote exterior finish.
TriggerTech Remington 700 Primary
This 6mm ARC pistol includes a TriggerTech Remington 700 Primary trigger in your choice of flat or curved profile. Pull weight is externally adjustable from 1.5 to 4.0 lb.
The trigger incorporates TriggerTech’s Frictionless Release Technology and CLKR adjustment system. Photographs may depict older flat triggers fitted with trigger shoes; current flat triggers do not include those shoes.
FDE Metallic CM7 Chassis
The CM7 chassis is machined from a single block of billet aluminum and finished in FDE Metallic Cerakote. Its flared magazine well accepts compatible AICS-pattern magazines, with an ambidextrous magazine release.
The chassis provides M-LOK compatibility, dual integrated QD sling sockets and a full bottom ARCA rail. A large trigger guard provides clearance for gloved operation.
The modular rear adapter uses a single-bolt interface for compatible rear components. The grip interface accepts compatible AR15 grips without an integrated dovetail.
6mm ARC Pistol Fit and Dimensions
Complete firearm weight is 6 lb 6 oz. Overall length adjusts from 25.00 to 32.50 inches, with a length-of-pull adjustment range of 6.0 to 13.5 inches.
The CM Precision Vertical Crossover Grip, developed in collaboration with MK Machining, is supplied in AI Dark Earth. Both rear configurations include an adjustable cheek riser.
Included AICS Magazine
One 10-round 6mm ARC AICS-pattern magazine in AI Dark Earth is included with this 6mm ARC pistol or SBR. The bolt-action CM7S uses a different magazine architecture from the semi-automatic CM15.
For additional magazines, visit the MDT 6mm ARC AICS magazine page and review the available options.
Suppressed Use
Chattahoochee Munitions prefers an enclosed, conventional baffle suppressor for the CM7S. Its manually operated action does not have the gas-operated cycling system found in the CM15.
For this 6mm ARC pistol, confirm that the suppressor manufacturer approves both the cartridge and the 12.5-inch barrel. The 5/8×24 muzzle threads identify the interface; compatibility also depends on bore suitability and the mounting system.
Supersonic ammunition continues to produce a sonic crack when suppressed. Consider the suppressor’s added length and weight when evaluating the complete firearm. Our 6mm ARC suppressor guide explains CM’s preferences by platform.
