Noveske Rifleworks N4 Chainsaw Complete AR-15 Upper Receiver - 300 Blackout - 10.5" - A2

The Noveske Rifleworks N4 Chainsaw Complete AR-15 Upper Receiver in 300 Blackout pairs a 10.5" 416R stainless barrel with a hand-polished Match Chamber, built for suppressor-ready, short-barreled applications.

Features:

• 10.5" 416R stainless steel barrel, 1:7 twist, hand-polished Noveske Match Chamber
• Carbine-length gas system, low-profile Noveske-marked gas block
• 5/8x24 threaded muzzle, A2 birdcage flash hider installed
• 9.75" Gen 4 NSR M-LOK handguard, 45-degree M-LOK intervals
• Radian Raptor LT charging handle with anti-rotation interface
• Forged 7075-T6 upper receiver, Type III hardcoat anodized
• Full-auto compatible, phosphate-coated BCG, chrome-lined carrier bore and key

The low-profile gas block sits flush against the free-floating handguard for a clean, snag-free profile, and the serialized barrel supports individual quality-control traceability. This compact build suits home defense, hunting, and range training where a short 300 Blackout platform is the goal.

Because this 10.5" barrel measures under 16", this complete upper is intended only for an AR pistol or a legally registered short-barreled rifle — attaching it to a standard rifle lower without the correct configuration violates federal law.
