Noveske Rifleworks N4 Infidel Complete AR-15 Upper Receiver - 5.56 - 13.7" - FDE

The Noveske Rifleworks N4 Infidel Complete AR-15 Upper Receiver in FDE pairs a 13.7" 416R stainless barrel with a pinned and welded Noveske KX3 flash suppressor, built as a ready-to-mount 5.56 upper.

Features:

• 13.7" 416R stainless steel barrel, 1:7 twist, Noveske Match Chamber
• Mid-length gas system, pinned .750" low-profile gas block
• 1/2x28 threaded muzzle, Noveske KX3 flash suppressor, pinned and welded
• 15" Noveske NSR M-LOK free-float handguard
• Noveske 4th Generation billet upper receiver
• Hardcoat anodized and Cerakoted for corrosion resistance
• Phosphate-coated bolt carrier group

The pinned and welded KX3 flash suppressor sits flush under the 15" NSR handguard, and hand-polished feed ramps on the M4 barrel extension improve feeding reliability across a range of 5.56 loads. The combination anodized-then-Cerakoted finish gives this upper an extra layer of corrosion resistance beyond a standard hardcoat alone.

Because this 13.7" 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.
