This Daniel Defense 5.56 16-inch Government Mid-Length Barrel Assembly (brand part no. 07-077-06158) ships as a complete assembly rather than a bare barrel, built on a Government profile with a mid-length gas system. It includes a low-profile gas block and the barrel nut needed for installation, so builders are not left sourcing those parts separately. At 16 inches, it keeps a rifle-length build legal for non-NFA configurations while the mid-length gas system gives a slightly softer cycling impulse than a standard carbine-length setup.
