Designed for compact performance and suppressor-friendly operation, the Noveske 4th Gen Upper pairs match‑grade barrels and proven gas systems with a 4th‑Generation billet receiver and the NSR free‑floating handguard. Each build is optimized for reliable feeding, controllable handling, and accessory flexibility in a short‑barrel package.
