Daniel Defense
Overview
The Daniel Defense MK18 URG is a complete upper receiver designed for the AR-15 platform, featuring a 10.3-inch barrel optimized for 5.56 NATO ammunition. Its 1:7 twist rate aids in stabilizing a range of bullet weights, while the pistol-length gas system ensures reliable cycling and reduced recoil in compact builds. This upper is particularly suited for builds that prioritize maneuverability and quick handling, commonly seen in short-barreled rifles and personal defense weapons.
