Chattahoochee Munitions manufactures this 375 Raptor pistol, the CM7S, a complete factory 12.5-inch bolt action finished in Black Tungsten Cerakote with a telescoping Tailhook brace. It pairs a Mos-Tek 416R stainless barrel with a 1:8 twist, a TriggerTech trigger, and the CM7 billet aluminum chassis, and it can also be ordered as an SBR.
The 375 Raptor was designed by Arne Brennan and fires a heavy 400 gr subsonic bullet that is made to be shot suppressed from a short barrel. See every configuration in the Raptor Paddock, and read 375 Raptor barrel length to compare 12.5 and 16-inch firearms.
Why a 375 Raptor Pistol
A 375 Raptor pistol puts a .375-caliber bolt action into a 25.00-inch package that weighs about 6 lb 6 oz. The telescoping Tailhook brace adjusts with the cheek riser, and the 12.5-inch barrel delivers the full performance of the 400 gr subsonic load. As a pistol, this 375 Raptor pistol is not a short-barreled rifle under the National Firearms Act; check your state and local laws, and choose the SBR configuration if you prefer a buttpad.
Pistol or SBR Configuration
This 375 Raptor Pistol can be ordered as a pistol with a telescoping Tailhook brace or as an SBR with a telescoping buttpad, each with an adjustable cheek riser and a 6.0 to 13.5-inch adjustment range. The CM Precision Vertical Crossover Grip positions the firing hand consistently. The SBR configuration is subject to National Firearms Act requirements; see NFA Firearms.
CM7S Action and Trigger
The CM7S action is steel with a Remington 700 footprint and a full PVD coating. It has three locking lugs, a 60-degree throw, and a one-piece spiral-fluted bolt with a .718-inch body, an M16-style extractor, and a .062-inch firing pin, with the standard .308 bolt face the 375 Raptor uses. Wire EDM raceways, an integrated .300-inch recoil lug, a side-release bolt stop, an oversized bolt knob, and a pinned 20 MOA Picatinny rail complete the action of this 375 Raptor Pistol. The TriggerTech Remington 700 Primary trigger comes flat or curved, adjusts from 1.5 to 4.0 lb, and removes without tools.
Barrel and 1:8 Twist
The 12.5-inch barrel is made by Mos-Tek from 416R stainless steel with 5R rifling and a 1:8 twist, finished in E100 Blackout Cerakote, with a shouldered crown, 11/16×24 muzzle threads, and Remage barrel-nut mounting. The 1:8 twist gives the long 400 gr subsonic bullet a wide stability margin over Maker Bullets’ 1:11 guidance. Read 375 Raptor twist rate and 375 Raptor barrel length for the details.
Ammunition and Magazine
From the 12.5-inch barrel, the Chattahoochee Munitions 400 gr Maker REX subsonic load averages about 1,016 fps, roughly 917 ft-lb at the muzzle and about 842 ft-lb at 100 yards. Use the bolt action load: 400 gr subsonic for bolt action. Bolt action and semi-auto 375 Raptor ammunition are loaded separately. Full tables are in 375 Raptor ballistics.
One 10-round Magpul PMAG 7.62 AC AICS-pattern magazine is included, and spares are available as CM7S 375 Raptor magazines.
Suppressing the CM7S
Because the CM7S is a manually operated bolt action, Chattahoochee Munitions recommends an enclosed suppressor, such as the enclosed PLACID 375. Confirm any suppressor is rated for .375 caliber and your barrel length. The 12.5-inch CM7S is also offered with the PLACID OTB over-the-barrel suppressor. The 375 Raptor suppressor guide covers the choice in detail.
Black Tungsten Cerakote Finish
This CM7S is finished in Black Tungsten Cerakote with a black grip, cheek riser, and forend grip covers. Mechanical specifications match the Cobalt Kinetics Green Cerakote and FDE Metallic Cerakote variations.
