CM7S 6mm ARC Short Barreled Rifle — Cobalt Kinetics Green
The 6mm ARC short barreled rifle from Chattahoochee Munitions combines a 12.5-inch barrel, CM7S bolt action and CM7 billet-aluminum chassis. This listing offers SBR and pistol configurations within Overwatch 6, CM’s supersonic precision and predator-hunting family.

6mm ARC Short Barreled Rifle or Pistol Options
Select the rear configuration that matches the firearm you intend to purchase:

The 12.5-inch barrel, action and chassis are shared features. The SBR option supplies the buttpad configuration; the pistol option supplies the Tailhook brace configuration. Review the selected product 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. An integrated recoil lug and pinned 20 MOA Picatinny rail are standard features.
The one-piece bolt has a .718-inch body diameter, spiral fluting, an M16-style extractor and an oversized bolt knob. The action incorporates wire EDM raceways, a side bolt-stop release and tool-less fire-control removal.
A .062-inch firing pin accommodates small-rifle-primer brass. Full PVD coating provides the protective action finish on this 6mm ARC short barreled rifle.
Barrel Manufactured in Collaboration with MosTek
The 12.5-inch barrel is manufactured in collaboration with MosTek. It uses 416R stainless steel and 5R rifling, with a confirmed 1:7 twist.
The barrel features a shouldered crown and 5/8×24 muzzle threads. It mounts with a Remage barrel nut and has an E100 Blackout Cerakote exterior finish.
TriggerTech Remington 700 Primary
This 6mm ARC short barreled rifle 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. Product photographs may show older flat triggers fitted with trigger shoes; current flat triggers do not include those shoes.
Cobalt Kinetics Green CM7 Chassis
The CM7 chassis is machined from a single block of billet aluminum and finished in Cobalt Kinetics Green 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. Its large trigger guard offers 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 Short Barreled Rifle Fit and Dimensions
Complete firearm weight is 6 lb 6 oz. Overall length adjusts from 25.00 to 32.50 inches, with a listed length-of-pull adjustment range of 6.0 to 13.5 inches.
The CM Precision Vertical Crossover Grip was developed in collaboration with MK Machining and is supplied in AI Dark Earth. Both rear configurations include an adjustable cheek riser for an additional fit adjustment.
Included 10-Round AICS Magazine
One 10-round 6mm ARC AICS-pattern magazine in AI Dark Earth is included with this 6mm ARC short barreled rifle or its pistol option. The bolt-action CM7S uses a different magazine architecture from the semi-automatic CM15.
For additional magazines, see the MDT 6mm ARC AICS magazine and review its 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 short barreled rifle, confirm suppressor approval for both the cartridge and the 12.5-inch barrel. The 5/8×24 muzzle threads identify the mounting 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 as part of the complete firearm. Read our 6mm ARC suppressor guide for CM’s platform-specific preferences.
