CM7S 6mm ARC Bolt Action SBR — 12.5-Inch WOOX Walnut
The 6mm ARC bolt action SBR from Chattahoochee Munitions combines the CM7S action and a 12.5-inch barrel with WOOX walnut furniture. An Exactus stock, Furiosa forend and MDT bottom metal distinguish this configuration from the telescoping CM7 chassis models.
This complete firearm includes a TriggerTech Remington 700 Primary trigger and one 10-round MDT 6mm ARC AICS magazine. It is part of Overwatch 6, CM’s supersonic precision and predator-hunting family.
Optics and suppressors depicted in product photographs are not included in the purchase price.
WOOX Walnut Furniture
This 6mm ARC bolt action SBR incorporates WOOX components in collaboration with Chattahoochee Munitions. The walnut Exactus stock provides an adjustable cheek riser and a buttpad adjustable for height and length of pull.
The stock includes a bottom Picatinny rail and QD sling mount. The walnut Furiosa forend provides M-LOK interfaces at the 3, 6 and 9 o’clock positions.
The monocore configuration uses MDT bottom metal with AICS-pattern magazine compatibility.
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, while an integrated recoil lug and pinned 20 MOA Picatinny rail are standard features.
The one-piece bolt incorporates 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 complete the principal action features.
A .062-inch firing pin accommodates small-rifle-primer brass. Full PVD coating provides the protective action finish on this 6mm ARC bolt action SBR.
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 bolt action SBR 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 show older flat triggers fitted with trigger shoes; current flat triggers do not include those shoes.
6mm ARC Bolt Action SBR Fit and Dimensions
Complete firearm weight is 7 lb 12 oz. Overall length adjusts from 31.750 to 32.50 inches, while length of pull adjusts from 13.75 to 14.75 inches.
The adjustable cheek riser and buttpad provide fit adjustments within the WOOX stock configuration. These dimensions differ from the telescoping CM7 chassis models, so compare the complete firearm specifications when selecting between them.
MDT Bottom Metal and Included Magazine
MDT bottom metal provides the AICS-pattern magazine interface for this 6mm ARC bolt action SBR. One 10-round MDT 6mm ARC AICS magazine is included.
For additional magazines, see the MDT 6mm ARC AICS magazine. The CM7S uses a different magazine architecture from the AR15-pattern system found in the semi-automatic CM15.
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 bolt action SBR, 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.
