CM10 375 Raptor AR10 Rifle 16″

The Chattahoochee Munitions CM10 375 Raptor 16″ Rifle is a purpose-built large-frame AR designed around the power, versatility, and unique ballistic capabilities of the .375 Raptor cartridge. Built with a 16-inch 1:7 twist barrel, adjustable gas system, AICS magazine compatibility, and premium components throughout, the CM10 is engineered to reliably handle the heavy projectiles and specialized loads that make the 375 Raptor such an impressive cartridge.

Chattahoochee Munitions has extensive experience building rifles in specialized and less-mainstream calibers, including 375 Raptor, 8.6 Blackout, 338 Spectre, 338 Federal, 400 Legend, 243 Winchester, 22-250 Remington, 7mm-08, and 308 Winchester. That experience with both AR and bolt-action platforms shaped the CM10 receiver system.

Rather than simply adapting an off-the-shelf large-frame AR, we developed the CM10 upper and lower receiver set around the features we wanted in a serious large-caliber rifle: tight tolerances, strength, dependable feeding, quality components, and compatibility with proven DPMS-pattern parts.

The result is a solid, exceptionally sturdy-feeling 375 Raptor semi-automatic rifle equally at home with heavy subsonic ammunition or the cartridge’s higher-velocity capabilities.

AICS Magazine Compatibility

One of the most important differences between the CM10 and a conventional AR10 is the magazine system.

The CM10 lower receiver is designed to accept AICS-pattern magazines, allowing smooth and reliable feeding of the large-diameter, flatter-nose projectiles commonly used in cartridges such as the 375 Raptor. The rifle includes one 10-round MDT metal 7.62 AICS magazine in Coyote. This magazine comes with an integral binder plate, but we add an additional binder plate to keep rounds from sliding forward.

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

Suppressor & Subsonic Performance

This 375 Raptor AR10 Rifle 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 produce sufficient gas pressure and energy to reliably cycle a semi-automatic action.

For customers looking for a complete suppressed 375 Raptor system, the CM10 paired with the PLACID 375 provides a rifle, ammunition, gas system, and suppressor combination developed around the same platform.
