Noveske N4 Afghan Complete Upper Features The Noveske N4 Afghan Complete Upper centers on a 14.5 inch 416R stainless steel barrel with a 1:7 twist rate chosen to stabilize a wide range of 5.56 NATO bullet weights. A hand-polished Noveske Match Chamber and extended feed ramps support smoother feeding and reliable function under sustained fire. The barrel s pinned low-profile gas block and mid-length gas system are tuned for consistent cycling while the Pig Pen muzzle device is permanently pinned and welded to bring the barrel to a 16 inch overall length. This configuration gives shooters the compact handling of a 14.5 inch barrel while meeting rifle-length requirements. Built on a 4th-generation billet 7075-T6 aluminum receiver the upper benefits from Type III hardcoat anodizing beneath its Flat Dark Earth style Cerakote finish for enhanced durability in black. The 13.5 inch NSR M-LOK handguard is free-floating and includes a continuous Picatinny top rail giving shooters ample real estate for optics and accessories. An ambidextrous charging handle and full-auto rated bolt carrier group round out the build for dependable operation. Spacing is specifically arranged for suppressor compatibility making this upper a strong choice for shooters planning to run a can on a 5.56 platform.
