The Noveske N4 Dplmt Upr Rcv 300BLK 7.94 pairs a compact 7.94 inch 416R stainless steel barrel with Noveske’s 4th generation billet upper to create a refined, ready-to-run complete upper receiver. Chambered in 300 AAC Blackout, it features a hand-polished Noveske Match Chamber, extended feed ramps, and a suppressor-ready Pig Pen muzzle device, all wrapped in a sleek NSR-7 M-LOK handguard with a continuous Picatinny top rail.

This upper is well suited for compact AR-15 builds focused on maneuverability, suppressed shooting, and precise performance with both subsonic and supersonic 300 BLK loads. The pistol-length gas system and pinned low-profile gas block promote smooth cycling, while the included ambidextrous charging handle and full-auto bolt carrier group make it a complete solution for range use, training, or home protection configurations. Noveske’s attention to detail and reputation for quality machining are evident throughout this upper receiver assembly.
