Noveske, Barrel Nut, NSR/NHR, 3rd Gen N4, Manganese Phosphate - SKU: 05000363 - UPC: 840906104071
Product Description
The Noveske NSR/NHR Barrel Nut (05000363) is an authentic OEM replacement mounting component engineered specifically for Noveske NSR, NHR, and Gen 3 N4 handguard systems. Precision-machined from high-strength steel, this barrel nut provides the foundational structural lockup required to secure your AR-15 barrel extension into the upper receiver while indexing Noveske free-float handguards.
Finished in a heavy-duty manganese phosphate coating, the 05000363 offers superior oil retention, corrosion resistance, and protection against extreme thermal cycling during rapid firing. The perimeter features Noveske’s proprietary mounting hole pattern designed for direct alignment with NSR/NHR handguard mounting screws, eliminating the need to time gas tube clearance through traditional barrel nut teeth.
Whether assembling a new Gen 3 N4 upper receiver build or replacing a worn component during barrel servicing, this factory original barrel nut guarantees exact thread pitch engagement and solid rail stabilization.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fit for MIL-SPEC AR-15 upper receivers paired with Noveske NSR, NHR, or Gen 3 N4 free-float handguards. Requires a standard Noveske barrel nut wrench for installation.
- Verify upper receiver and barrel assembly are completely clear, magazine removed, and chamber visually and physically confirmed empty.
- Clean receiver extension threads and apply a thin layer of aerosol-grade moly grease (MIL-PRF-2105) to upper threads.
- Slide barrel extension into upper receiver socket, aligning gas port pin with receiver indexing notch.
- Thread Noveske 05000363 barrel nut onto upper receiver and use a dedicated Noveske barrel nut wrench to torque/season threads (torque to manufacturer spec: typically 40-50 ft-lbs).
- Slide NSR/NHR handguard over the barrel nut, align top rail flush with upper receiver rail, and secure mounting screws evenly to final torque specs.
