Purpose-Built 375 Raptor AR10 SBR Carbon Gray

The Chattahoochee Munitions CM10 375 Raptor 12.5″ Carbon Gray SBR combines our purpose-built large-frame AR platform with a subdued Carbon Gray Cerakote finish. Engineered around the unique requirements of the .375 Raptor cartridge, this compact CM10 features a 12.5-inch 1:7 twist barrel, AICS magazine compatibility, adjustable gas system, adjustable buffer, and premium components throughout.

The 375 Raptor is capable of launching exceptionally heavy projectiles, making it particularly well suited to suppressed and subsonic applications. 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 features a Carbon Gray Cerakote receiver set, handguard, and buffer tube, giving the rifle a clean, understated appearance while retaining the same purpose-built components and performance of the CM10 platform.

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

AICS Magazine System

One of the defining characteristics of the CM10 375 Raptor AR10 SBR Carbon Gray 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 includes an integrated binder plate and we add an additional slim binder plate to keep rounds from moving forward.

Built Around Suppressed 375 Raptor Performance

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

The CM10 375 Raptor 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 AR10 SBR Carbon Gray 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.

Why Choose the CM10 375 Raptor SBR Carbon Gray?

The CM10 375 Raptor AR10 SBR Carbon Gray offers more than a different finish.

Underneath the subdued Carbon Gray Cerakote is a large-frame AR platform engineered around the requirements of the 375 Raptor cartridge. The AICS magazine system, center-feed barrel extension, adjustable gas block, adjustable buffer, 1:7 twist barrel, billet receiver set, and suppressor-focused development distinguish the CM10 from a conventional AR10 that has simply been converted to another caliber.

The compact 12.5-inch configuration makes the rifle particularly well suited to pairing with a suppressor, while the 375 Raptor provides the heavy-projectile capability that makes the cartridge such a compelling choice for subsonic use.

For shooters searching for a 375 Raptor AR10 SBR built specifically around suppressed and heavy-projectile performance, the Carbon Gray CM10 provides a complete purpose-built platform rather than a collection of adapted components.
