CM7S .458 SOCOM XL 16″ Rifle

Purpose-Built 458 SOCOM Bolt Action Rifle

The Chattahoochee Munitions CM7S .458 SOCOM XL 16″ Rifle is a purpose-built 458 SOCOM Bolt Action Rifle designed to take the capabilities of the .458 SOCOM concept beyond the cartridge overall-length limitations of the traditional AR-15 platform.

Chambered in .458 SOCOM XL, the CM7S takes advantage of the additional cartridge length available in a short-action platform. This provides greater flexibility when loading the extremely heavy .458-caliber projectiles that make this platform particularly well suited to suppressed and subsonic applications.

At the heart of this 458 SOCOM Bolt Action Rifle is a 16-inch barrel with a fast 1:10 twist rate, providing the rotational stability required for the exceptionally heavy projectiles used with .458 SOCOM XL.

The rifle feeds from genuine MDT metal magazines modified by Chattahoochee Munitions specifically for the dimensions and feeding requirements of .458 SOCOM XL.

For shooters looking beyond a conventional .458 SOCOM platform, the CM7S combines massive projectile capability with the accuracy, simplicity, and versatility of a purpose-built bolt-action rifle.

Why Choose a 458 SOCOM Bolt Action Rifle?

Traditional .458 SOCOM was developed around the AR-15 platform. While that makes standard .458 SOCOM an excellent large-bore option for the AR platform, it also places restrictions on cartridge overall length.

.458 SOCOM XL moves beyond those limitations.

By utilizing the CM7S short-action platform and an AICS-pattern magazine architecture, .458 SOCOM XL provides additional cartridge overall length for loading heavy .458-caliber projectiles.

This allows our 458 SOCOM Bolt Action Rifle to be built around the cartridge rather than forcing the cartridge to remain within the dimensional limitations of an AR-15 magazine.

The result is a specialized large-bore platform developed for shooters who want to take advantage of extremely heavy .458-caliber projectiles, particularly in suppressed and subsonic applications.

16″ Barrel with 1:10 Twist

The CM7S .458 SOCOM XL features a 16-inch barrel with a 1:10 twist rate.

Projectile stabilization becomes increasingly important as projectile weight and length increase. The fast 1:10 twist rate used in this 458 SOCOM Bolt Action Rifle is specifically selected around the heavy-projectile capabilities of .458 SOCOM XL.

The 16-inch barrel provides a versatile balance between barrel length and handling while maintaining the specialized capabilities that define the platform.

Combined with the compact CM7S action, the result is a highly maneuverable large-bore rifle capable of handling projectiles far heavier than those typically associated with conventional short-action cartridges.

.458 SOCOM XL

The defining feature of this rifle is the cartridge itself.

Traditional .458 SOCOM is constrained by the dimensions necessary to function within the AR-15 platform. .458 SOCOM XL utilizes the additional room available in the CM7S short-action platform to increase usable cartridge overall length.

That additional length creates considerably more flexibility when working with long, heavy .458-caliber projectiles.

For shooters interested in a 458 SOCOM Bolt Action Rifle specifically because of the cartridge’s heavy-projectile potential, .458 SOCOM XL provides an entirely different approach to the platform.

Rather than simply adapting a conventional .458 SOCOM chamber to a bolt-action rifle, Chattahoochee Munitions developed the CM7S configuration around the expanded capabilities of .458 SOCOM XL.

Modified MDT Metal Magazine System

A cartridge as large as .458 SOCOM XL requires a magazine configured specifically around its dimensions.

The CM7S uses genuine MDT metal AICS-pattern magazines modified by Chattahoochee Munitions for .458 SOCOM XL. The modifications provide the cartridge clearance and feed geometry necessary to properly accommodate and present the oversized cartridge.

This magazine system allows the 458 SOCOM Bolt Action Rifle to take advantage of the extended cartridge overall length available in the CM7S platform.

Chattahoochee Munitions also utilizes this modified MDT magazine architecture in our CM10 semi-automatic .458 SOCOM XL platform.

TriggerTech Primary Trigger

The CM7S .458 SOCOM XL comes standard with a TriggerTech Primary Remington 700 trigger, providing a clean, consistent break that complements the accuracy-focused CM7S bolt-action platform.

Each rifle is configured with the trigger pull set at approximately 1.5 pounds and is available with your choice of a flat or curved trigger shoe.

A quality trigger is especially important on a 458 SOCOM Bolt Action Rifle, where precise shot placement and a predictable trigger break help the shooter take full advantage of the inherent stability and accuracy of the bolt-action platform.

Designed Around Suppressed and Subsonic Performance

The CM7S platform is particularly well suited to suppressed shooting.

Unlike a semi-automatic action, a bolt-action rifle remains mechanically locked during firing. For shooters pursuing a quiet suppressed platform, eliminating the action cycling associated with a semi-automatic firearm can be a significant advantage.

Combine that with the ability to launch exceptionally heavy .458-caliber projectiles at subsonic velocities, and the CM7S becomes a compelling platform for specialized suppressed applications.

The fast 1:10 twist barrel developed in collaboration with Mos-Tek provides the stabilization required by these heavy projectiles, while the .458 SOCOM XL cartridge configuration provides the additional overall length necessary to take advantage of projectile designs that would otherwise be constrained by AR-15 magazine dimensions.

The result is a 458 SOCOM Bolt Action Rifle engineered around the characteristics that make heavy subsonic cartridges so unique.
