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

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 barrel operates on a rifle-length direct impingement gas system, pairing with the DMR-class configuration to deliver consistent, accurate performance at extended distances. A free-float M-LOK handguard provides rail attachment flexibility while keeping the barrel harmonics undisturbed. The upper is finished in a grey anodized/cerakote exterior. No stock, trigger, or lower components are included in this upper receiver assembly.
