Noveske 11.5" 5.56 Extra Thicc DDF Stainless Barrel

The Noveske 11.5" Extra Thicc DDF barrel pairs a heavier Extra Thicc contour with Noveske's Disruptive Deep Fluting, which Noveske designed to reduce primary and secondary wave events in the barrel. The result is a stiff short barrel that still weighs 24 oz. It is 416R stainless with a 1:7 twist and the hand-polished Noveske Proprietary Match chamber, and each barrel is individually serialized for quality-control traceability.

Gas runs on a mid-length system, which is long for an 11.5" barrel and gives a softer impulse than carbine gas at this length. The low-profile gas block is pinned on a .936" journal, so a replacement block has to be a .936 part, not the common .750. The M4 extension has extended, hand-polished feed ramps, the crown is 60 degrees, and the 1/2x28 threads take standard 5.56 muzzle devices and suppressor mounts.

At 11.5" this barrel builds an AR pistol or, with a stock, a short-barreled rifle. A stocked build needs an approved ATF Form 1 or Form 4 before assembly, and you should check your state's law first.
