Noveske N4 Infidel Complete Upper Features The Noveske N4 Infidel Complete Upper is chambered in 5.56 NATO and centers on a stainless steel 13.7-inch barrel with a mid-length gas system for smoother cycling and reduced felt recoil compared to a carbine-length setup. The Noveske KX3 flash suppressor is pinned and welded to the muzzle bringing the barrel s legal overall length to 16 inches while suppressing muzzle flash for better follow-up shot visibility. A hand-polished Noveske Match Chamber and extended feed ramps improve feeding reliability across a range of 5.56 ammunition. The 4th-generation billet 7075-T6 aluminum receiver is machined to tight tolerances for a precise fit on any compatible AR-15 lower. A 15-inch M-LOK free-floating handguard runs the length of the upper giving shooters a continuous top rail for mounting optics and ample real estate for lights slings and grips along the sides. The ambidextrous Noveske Love Handle charging handle gives shooters fast positive manipulation from either side of the rifle useful in both training and duty environments. Finished in a durable black Cerakote coating the upper resists wear and corrosion through hard use in the field. The included Pig Pen flash hider variant and pinned muzzle device combination reflect Noveske s reputation for building rifles trusted by professional shooters.
