CM7S 375 Raptor SBR 12.5″ – Cobalt Kinetics Green / Coyote
The CM7S 375 Raptor SBR from Chattahoochee Munitions combines the heavy-projectile capability of 375 Raptor with a compact 12.5-inch bolt-action platform. Built around the purpose-designed CM7S action, fast-twist barrel, adjustable billet chassis, and TriggerTech Primary trigger, this configuration is intended for shooters who want a maneuverable 375 Raptor platform with particular emphasis on suppressed and subsonic use.
This 375 Raptor SBR features a Cobalt Kinetics Green Cerakote chassis paired with Coyote furniture and an E100 Blackout Cerakote barrel. At just 6 pounds 6 ounces with an overall length beginning at 25.00 inches, the firearm provides an exceptionally compact configuration while retaining the adjustability and component selection of the CM7S platform.

A Compact 375 Raptor SBR Built Around the CM7S
The CM7S action provides the mechanical foundation for the firearm. Built from steel around the familiar Remington 700 footprint, the action incorporates features intended specifically for a modern hunting and precision bolt-action platform.
A 3-lug bolt with a 60-degree throw reduces bolt lift while providing generous clearance around the optic. The one-piece bolt uses a .718-inch body and incorporates spiral fluting, an oversized bolt knob, and an M16-style extractor.
Wire EDM-cut raceways provide uniform tolerances and promote smooth bolt travel. A large ejection port, side bolt-stop release, and tool-less fire control removal add practical functionality to the action.
The optics interface consists of a pinned 20 MOA Picatinny rail. The CM7S also incorporates an integrated recoil lug and a .062-inch firing pin to accommodate small-rifle-primer brass.
The complete action weighs approximately 25 ounces and receives a full PVD coating for corrosion protection and smooth operation. Together, these features provide the 375 Raptor SBR with a purpose-built action rather than relying on a conventional factory receiver.
12.5″ Fast-Twist 375 Raptor Barrel
The defining feature of this 375 Raptor SBR is its compact 12.5-inch barrel. Manufactured by Mos-Tek from 416R stainless steel, the barrel incorporates 5R rifling and a fast 1:7 twist rate.
The fast twist is well suited to the heavy projectiles commonly associated with 375 Raptor, while the shorter barrel helps reduce the overall length of the firearm. This becomes particularly valuable when a suppressor is added to the muzzle.
- 12.5″ barrel length
- 416R stainless steel
- 5R rifling
- 1:7 twist rate
- Shouldered crown
- 11/16×24 muzzle threads
- Remage barrel-nut mounting system
- E100 Blackout Cerakote finish
The barrel receives an E100 Blackout Cerakote finish and uses a Remage barrel-nut mounting system. The muzzle of the 375 Raptor SBR is threaded 11/16×24 for appropriately threaded muzzle devices and suppressor mounting systems.
375 Raptor SBR for Suppressed Shooting
The short barrel and fast twist make the 375 Raptor SBR particularly attractive as the foundation for a suppressed bolt-action system. Keeping the barrel to 12.5 inches helps control overall firearm length after a suppressor is installed.
Chattahoochee Munitions offers the PLACID 375 as a dedicated 375-caliber suppressor option.
Customers seeking a more integrated suppression system can also explore PLACID OTB, the over-the-barrel reflex suppression system developed around the CM7S platform.
For shooters prioritizing a compact suppressed package, the combination of a 12.5-inch barrel and purpose-built CM7S action gives the 375 Raptor SBR a substantially different role from a conventional full-length bolt-action rifle.
For a purpose-built subsonic option, pair this rifle with our 375 Raptor 400gr Maker REX Subsonic Ammunition – Bolt Action, developed specifically for CM7S bolt-action applications.
TriggerTech Primary Trigger
Each 375 Raptor SBR is equipped with a TriggerTech Remington 700 Primary trigger featuring TriggerTech’s Frictionless Release Technology.
Pull weight is externally adjustable from 1.5 to 4.0 pounds in 1-ounce increments. Customers can select either a flat or curved trigger according to preference.
Some product photography may depict an earlier flat TriggerTech trigger fitted with a trigger shoe. Current production flat triggers no longer use the shoe shown in those photographs.
CM7 Billet Aluminum Chassis
The CM7 chassis is machined from a single block of billet aluminum and provides the structural foundation for the compact firearm. This 375 Raptor SBR receives a Cobalt Kinetics Green Cerakote finish paired with Coyote furniture.
A flared magazine well accepts AICS-pattern magazines, while an ambidextrous magazine release provides convenient access from either side. A large trigger guard provides additional clearance when shooting with gloves.
The chassis incorporates a full-length bottom ARCA rail for direct attachment to compatible tripods and shooting supports. M-LOK attachment points provide additional accessory mounting capability, while dual integrated QD sockets provide sling attachment locations.
The modular stock adapter uses a simple single-bolt interface, and the chassis accepts AR-15 pistol grips without an integrated dovetail.
Adjustable Stock and CM Precision Grip
The telescoping stock is an important part of the compact character of the 375 Raptor SBR. Length of pull can be adjusted from 6.0 to 13.5 inches, providing a substantial range of adjustment for different shooters, clothing, optics, and shooting positions.
An adjustable Coyote cheek riser helps establish consistent alignment behind the optic. When the stock is collapsed, the complete firearm measures approximately 25.00 inches in overall length. Fully extended, overall length increases to approximately 32.50 inches.
The firearm is equipped with the CM Precision Vertical Crossover Grip, developed by Chattahoochee Munitions in collaboration with MK Machining. The grip combines vertical precision-rifle geometry with a profile suited to field positions and supported shooting.
AICS Magazine Compatibility
The CM7 chassis uses the established AICS magazine pattern rather than a proprietary magazine system. Each 375 Raptor SBR includes one Magpul PMAG 10 7.62 AC AICS magazine.
AICS compatibility provides access to a mature magazine ecosystem while maintaining the modularity of the CM7 chassis.
6 lb 6 oz Compact Bolt-Action Platform
At approximately 6 pounds 6 ounces, the complete firearm combines relatively light weight with exceptionally compact dimensions. The 12.5-inch barrel and telescoping stock allow the 375 Raptor SBR to measure approximately 25.00 inches when collapsed while still providing a full 13.5-inch maximum length of pull when extended.
That combination can be particularly useful when moving through dense terrain, operating from confined hunting positions, transporting the firearm, or building a suppressed system where controlling total length is important.
The combination of a short barrel, fast 1:7 twist, adjustable chassis, PVD-coated CM7S action, and TriggerTech trigger creates a 375 Raptor SBR designed around compactness without abandoning the features of a modern precision bolt-action platform.
