White Label Armory 16" 5.56 Government Mid-length Barrel

White Label Armory's 16" barrel is WLA's non-NFA 16" mid-length barrel for a standard carbine build. It is chambered in 5.56 NATO with a 1:7 right-hand twist, turned from 4150 CMV steel to a Government profile, and black nitrided. The mid-length gas system runs through a .750" gas block journal with a .078" port, the barrel extension has M4 feed ramps, and the muzzle carries 1/2x28 threads and an 11-degree target crown. WLA lists it at 29.0 oz bare.

Pair it with a mid-length gas tube and a gas block sized to the barrel's journal. The 1:7 twist stabilizes the full common range of 5.56 bullet weights, and the 1/2x28 threads take standard 5.56 flash hiders, brakes, and suppressor mounts. At 16" the barrel meets the federal rifle minimum on its own, so it needs no pinned and welded device and no NFA paperwork.
