CM 375 Raptor
Chattahoochee Munitions manufactures the CM10, a complete factory 375 Raptor AR10 semi-automatic offered as a 12.5-inch SBR and a 16-inch rifle in Carbon Grey, Cobalt Kinetics Green, or FDE Metallic Cerakote. Every CM10 uses a Mos-Tek 416R stainless barrel with a 1:8 twist, finished in E100 Blackout Cerakote. The 375 Raptor was designed by Arne Brennan.
A reliable 375 Raptor semi-auto takes more than a barrel change on a .308. The 400 gr subsonic cartridge is long and runs at low pressure, so the CM10 uses a centerfeed system, a modified MDT metal magazine, a Superlative Arms adjustable gas block, and an Odin Works adjustable buffer, so it can be tuned to cycle subsonic and supersonic loads, suppressed or unsuppressed. See the full lineup in the Raptor Paddock, and compare platforms in 375 Raptor bolt action vs semi-auto.
