Purpose-Built 375 Raptor AR10 Rifle Carbon Gray

The Chattahoochee Munitions CM10 375 Raptor AR10 Rifle Carbon Gray combines our purpose-built large-frame AR platform with a subdued Carbon Gray Cerakote finish and Black B5 furniture. Engineered around the unique requirements of the .375 Raptor cartridge, this CM10 features a 16-inch 1:7 twist barrel, AICS magazine compatibility, adjustable gas system, adjustable buffer, and premium components throughout.

The 375 Raptor AR10 Rifle Carbon Gray is capable of launching exceptionally heavy projectiles, making it particularly well suited to suppressed and subsonic applications while also offering impressive performance with supersonic ammunition. Building a reliable semi-automatic platform around those capabilities requires more than simply installing a 375 Raptor barrel into a conventional AR10.

That is where the CM10 platform is different.

Chattahoochee Munitions developed the CM10 receiver system using our experience building specialized calibers across both AR and bolt-action platforms. Our experience includes 375 Raptor, 8.6 Blackout, 338 Spectre, 338 Federal, 400 Legend, 243 Winchester, 22-250 Remington, 7mm-08, and 308 Winchester.

The resulting CM10 is a sturdy, tightly fitted large-frame AR designed around dependable feeding, premium components, suppressor compatibility, and the ability to properly tune the operating system for specialized ammunition.

Carbon Gray Cerakote Configuration

This CM10 configuration pairs a Carbon Gray Cerakote receiver set, handguard, and buffer tube with Black B5 Systems furniture, creating a clean, understated appearance while retaining the purpose-built components and performance of the CM10 platform.

The Carbon Gray and Black configuration provides a neutral alternative to our Cobalt Kinetics Green configuration without changing the mechanical features that make the CM10 375 Raptor unique.

AICS Magazine System

One of the defining characteristics of the CM10 375 Raptor is its AICS magazine architecture.

Rather than using a conventional AR10 magazine, the CM10 lower receiver is specifically machined to accept AICS-pattern magazines.

This configuration provides reliable center feeding and is particularly well suited to the large-diameter, flatter-nose projectiles commonly used with the 375 Raptor. It also gives the cartridge additional flexibility compared with being constrained by a traditional AR-pattern magazine.

A paddle-style magazine release is located directly in front of the trigger guard for convenient operation.

The rifle includes one 10-round MDT metal 7.62 AICS magazine in Black. This magazine has an integrated binder plate and we add an additional slim binder plate to keep rounds from sliding forward.

Built Around Suppressed 375 Raptor Performance

Suppressor performance wasn’t an afterthought in the development of this rifle.

The CM10 375 Raptor AR10 Rifle Carbon Gray is designed and tested using the Chattahoochee Munitions PLACID 375 Suppressor. The rifle has also been tested with a SilencerCo Hybrid 46 and will cycle Chattahoochee Munitions 375 Raptor subsonic ammunition.

Performance with ammunition from other manufacturers may vary, particularly with subsonic loads. Ammunition must generate sufficient gas pressure and energy to reliably operate a semi-automatic action.

Pairing the CM10 375 Raptor with the PLACID 375 Suppressor and Chattahoochee Munitions 375 Raptor ammunition creates a complete system in which the rifle, operating system, suppressor, and ammunition have been developed and tested together.

Finished in Carbon Gray Cerakote with Black B5 Systems furniture, this configuration delivers a clean, understated appearance to match the purpose-built performance underneath it.

For shooters searching for a 375 Raptor AR10 rifle engineered around the cartridge rather than adapted to it, the CM10 16″ Carbon Gray provides a complete, purpose-built solution.
