Noveske Rifleworks N4 SPR Complete AR-15 Upper Receiver - 6mm ARC - 18" - Bazooka Green

The Noveske Rifleworks N4 SPR Complete AR-15 Upper Receiver in Bazooka Green pairs an 18" 416R stainless barrel in 6mm ARC with a rifle-length gas system, built for long-range precision.

Features:

• 18" 416R stainless steel barrel chambered in 6mm ARC, 1:7 twist, 3 land and groove rifling
• Hand-polished Noveske Match Chamber
• Rifle-length gas system, pinned low-profile gas block
• 5/8x24 threaded muzzle, Noveske Pig Pen suppressor-compatible muzzle device
• 15" NSR M-LOK handguard, full-length Picatinny top rail
• Billet 7075-T6 upper receiver with extended feed ramps
• Bazooka Green Cerakote over hardcoat anodizing
• Ambidextrous charging handle, full-auto compatible BCG

The rifle-length gas system and 1:7 twist are matched to extract full velocity from the 6mm ARC cartridge, and the Pig Pen muzzle device gives a direct suppressor mounting path without an adapter. The 15" NSR handguard's M-LOK slots and continuous top rail give you full-length accessory mounting for a dedicated long-range build.

This upper mounts to any standard Mil-Spec AR-15 lower and comes fully assembled with a bolt carrier group and charging handle installed, ready to mount and shoot.
