Noveske N4 Receiver Set Features The Noveske N4 receiver set is precision machined from billet material so the upper and lower mate with exceptional fit eliminating the play that can plague mismatched components. Installed ambidextrous controls give left and right handed shooters equal access to the safety and other manipulation points without aftermarket parts. Extended feed ramps are cut into the upper to improve feeding reliability across a range of magazines and ammunition types a detail that matters most under hard use. The included adjustable tension screw lets a builder dial out any looseness between the two receivers tightening the overall feel of the rifle or pistol it becomes. Noveske also installs the port door and a Noveske marked forward assist along with the takedown and pivot pins so the set arrives ready to accept a bolt carrier group and the rest of a build with minimal extra parts needed. The receivers are shaped to match the profile of Noveske s fourth generation handguards keeping the lines of a completed rifle clean and consistent with the rest of the lineup. Finished in a durable anodized black suited to hard use the N4 set reflects the fit and finish standards that have made Noveske a respected name among AR builders.
