APF Armory DMR 2.0 Complete Upper 6mm ARC 18" Stainless M-LOK

The APF Armory DMR 2.0 is a complete AR-15 upper receiver kit chambered in 6mm ARC, built around an 18" 416 stainless steel barrel optimized for long-range precision. The stainless barrel construction is paired with a rifle-length or mid-length gas system suited to the 18" profile, operating via direct impingement. A free-float M-LOK handguard provides a clean, modular platform for accessories while maintaining barrel-to-handguard clearance. The DMR 2.0 is purpose-built for designated marksman-style applications, delivering consistent accuracy across the 6mm ARC cartridge's effective range envelope. Muzzle threading follows standard 1/2-28 convention.
