The PLACID .375 375 Suppressor from Chattahoochee Munitions is a fully welded suppressor designed for centerfire rifle cartridges ranging from 5.56 NATO through .375 Magnum. Built with a 17-4 stainless steel suppressor body, 13-baffle design and HUB-compatible mounting interface, the PLACID .375 provides a versatile suppression option for a broad range of compatible rifle configurations.
For Chattahoochee Munitions customers, the PLACID .375 is particularly well suited to cartridges such as 375 Raptor, while its caliber rating allows it to be used across additional compatible rifle platforms and cartridges within its stated rating.
Rather than relying on generalized claims about sound levels, recoil percentages or accuracy improvements, the PLACID .375 is defined by its construction, dimensions, mounting system and caliber capability.
PLACID .375 375 Suppressor
The PLACID .375 uses a fully welded 17-4 stainless steel suppressor body containing 13 baffles. The suppressor measures 8.25 inches long and 1.5 inches in diameter, with a total suppressor weight of 16.9 ounces.
Its 1.375×24 HUB mounting interface provides compatibility with appropriate HUB-pattern mounting components. Each suppressor is supplied with an 11/16×24 titanium direct-thread mount and a titanium .375 end cap.
This combination gives the user a complete direct-thread configuration out of the box while retaining the flexibility of the widely used HUB mounting standard.

Rated from 5.56 NATO Through .375 Magnum
The PLACID .375 is rated for cartridges from 5.56 NATO through .375 Magnum. This broad caliber range allows the same suppressor to be considered for multiple compatible centerfire rifle configurations rather than limiting it exclusively to a single cartridge.
Adequate bore diameter alone should not be used to determine suppressor compatibility. The firearm, cartridge, barrel, mounting system and complete configuration must all be appropriate for the suppressor being used.
For customers purchasing a 375 Suppressor specifically for 375 Raptor, the PLACID .375 provides a CM-manufactured suppressor option that can be paired with compatible Chattahoochee Munitions rifle configurations.
Built Around a Fully Welded 17-4 Stainless Body
The main suppressor body is constructed from 17-4 stainless steel and uses a fully welded construction. Internally, the PLACID .375 incorporates a 13-baffle design.
The included mounting component and end cap use a different material approach. Both the supplied 11/16×24 direct-thread mount and the supplied .375 end cap are manufactured from titanium.
These are the actual construction specifications of the PLACID .375. Chattahoochee Munitions does not use material selection alone to make unsupported claims about sound reduction, accuracy, recoil reduction or suppressor life.
1.375×24 HUB-Compatible Mounting
The PLACID .375 uses a 1.375×24 HUB interface. HUB has become a widely used suppressor mounting standard and allows compatible mounting components to be installed in the suppressor body.
Every PLACID .375 includes an 11/16×24 titanium direct-thread mount. This provides a direct-thread option for appropriately threaded compatible firearms without requiring an additional mount to be purchased for that configuration.
Customers who choose a different HUB mounting solution should confirm that the selected mounting component is appropriate for the firearm, cartridge and intended configuration.
375 Suppressor Size and Weight
At 8.25 inches long, 1.5 inches in diameter and 16.9 ounces, the PLACID .375 should be evaluated as part of the complete rifle rather than by suppressor specifications alone.
Suppressor length and weight influence the overall length, balance and handling characteristics of a firearm. Those effects can vary significantly depending on barrel length, rifle configuration and mounting arrangement.
For that reason, selecting a 375 Suppressor should include consideration of how the suppressor integrates with the host firearm as a complete system.
PLACID .375 and 375 Raptor
375 Raptor is one of the primary applications for the PLACID .375 within the Chattahoochee Munitions product line. CM offers 375 Raptor firearms in multiple configurations, allowing the suppressor and firearm to be considered together rather than treating suppression as an unrelated accessory decision.
375 Raptor can be used with both subsonic and supersonic ammunition, and those two ammunition types produce different ballistic and acoustic characteristics. A suppressor reduces muzzle blast produced by expanding propellant gases, while a supersonic projectile also produces a ballistic shock wave during flight.
For more detail on those considerations, see our 375 Raptor Suppressor Guide.
Suppressed firearms should not be described as silent, and Chattahoochee Munitions does not characterize the PLACID .375 as universally “hearing safe.” Appropriate hearing protection should still be used.
Suppressor Ownership and Applicable Regulations
Firearm suppressors are regulated under the National Firearms Act (NFA). Customers are responsible for complying with applicable federal, state and local requirements. For current federal information regarding suppressor regulation and NFA requirements, visit the ATF National Firearms Act information page.
What Comes with the PLACID .375?

Why Choose the PLACID .375?
The PLACID .375 is intended for customers looking for a 375 Suppressor with straightforward, published specifications and a broad centerfire rifle caliber rating.
Its defining characteristics are measurable: a fully welded 17-4 stainless steel body, 13 baffles, 8.25-inch overall length, 1.5-inch diameter, 16.9-ounce weight, 1.375×24 HUB interface and a caliber rating extending from 5.56 NATO through .375 Magnum.
For CM customers running 375 Raptor, it also provides the advantage of selecting a suppressor from the same manufacturer producing the host firearm.
