Built for shooters who want increased stopping power with enhanced accuracy and control, this 6.8 SPC II 16" Fluted Upper delivers hard-hitting performance in a lightweight, well-balanced platform.
The 416R stainless steel barrel with a 7-flute profile reduces weight while improving cooling and rigidity. A 1:11 button-rifled twist is optimized for common 6.8 SPC loads, while the CMMG adjustable mid-length gas system provides smooth recoil and tunable, reliable cycling.
Paired with a 12" M-LOK free-float handguard, MBP Precision muzzle brake, and a CNC-machined 7075-T6 mil-spec upper receiver, this build is designed to stay flat, shoot accurate, and perform under pressure.
