This Noveske N4 Lo-Pro Gen III Complete AR-15 Upper Assembly is chambered in 300 AAC Blackout and comes fully assembled and ready to drop onto any standard AR-15 lower receiver. The Gen III upper is a precision machined billet receiver from 7075-T6 with extended feed ramps. The upper is finished with Hardcoat type III anodizing, with Cerakote ceramic black coating for the ultimate finish and performance. It comes equipped with one of Noveske's legendary bead blasted stainless steel match barrels for outstanding accuracy. This barrel is turned down to a lightweight contour for faster handling, and is outfitted with improved polygonal 1 in 7" twist rifling, M4 feed ramps, 5/8"-24 muzzle threads and a non-glare, bead-blasted finish. Additional features include a Noveske-marked Raptor ambidextrous charging handle, a pinned low profile gas block, an Noveske Marked Saker Trifecta flash hider, shot-peened, MP-tested bolt housed within a Mil-Spec bolt carrier. The upper also comes with a pistol length gas system.
This Gen III upper includes a 13.5" long Noveske NSR-13.5 handguard with the proprietary KeyMod rail system and, with an outside diameter of only 1.48" (without accessories attached), it is one of the slimmest, lightest, customizable handguards available for the AR-15 platform. The NSR free floats the barrel for greater accuracy potential and provides a full length, continuous top rail for the addition of optics and/or accessories (additional add-on rail sections sold separately). KeyMod accessories are quick and easy to install along the handguard's length, and don't require that the NSR be removed from the upper in order to attach or detach them. All KeyMod system accessories use captured backing plates that are inserted into an unused key-slot hole and then tightened into place via an allen wrench, eliminating the tedious and frustrating procedure of fishing separate backer plates down the interior of a handguard and securing them with loose fasteners like most competing modular forearm designs.
