Chattahoochee Munitions manufactures complete factory CM7S bolt action, CM10 large-frame semi-auto, CM15 AR15 and CM9 pistol-caliber firearms, plus PLACID suppressors. Our focus is short-barrel subsonic performance in specialized cartridges such as 375 Raptor and 458 SOCOM XL.
DIFFERENT CALIBERS. A HIGHER STANDARD.
Suppressors are not an afterthought. The PLACID series is designed to work as an integrated part of the CM system: firearm, barrel configuration, and cartridge. PLACID suppressors thread directly to the muzzle, and PLACID OTB systems mount over the barrel.
A bolt action adds no action noise, so every CM7S pairs with an enclosed suppressor. On CM10 and CM15 semi-autos, use an enclosed suppressor with subsonic ammunition and a flow-through suppressor with supersonic ammunition.
458 SOCOM XL explained: why the AR15’s 2.260-inch limit forces heavy 458 SOCOM bullets deep into the case, how loading a 650 gr projectile to 2.802 or 2.790 inches reclaims case capacity for powder, and which Chattahoochee Munitions firearms and magazines are configured for it.
375 Raptor subsonic explained: why the 400 gr Maker REX carries so much energy below the speed of sound, why 12.5-inch barrels are ideal, how cold weather affects subsonic loads, and which Chattahoochee Munitions firearms and suppressors fit.

Chattahoochee Munitions is a veteran-owned firearm manufacturer in Roswell, Georgia. We design and manufacture specialized firearms and suppression systems for cartridges that demand more from the platform, including the 375 Raptor, designed by Arne Brennan, and 458 SOCOM XL, which moves 458 SOCOM beyond the AR15 magazine length limit.
Every CM7S barrel is made by Mos-Tek and finished in E100 Blackout Cerakote, and every CM10 and CM15 uses a TriggerTech trigger. See our firearms and suppressors at work in our field testing videos.
