Why Choose a New Orleans Custom AR-15 Upper Receiver?

The upper receiver is the heart of an AR-15 platform — it houses the barrel, bolt carrier group, and gas system and provides the mounting platform for optics, handguards, and muzzle devices. Our New Orleans custom AR-15 uppers are engineered with attention to tight tolerances, reliable cycling, and long-term durability.

Installing a New Orleans custom AR-15 upper receiver is straightforward for anyone familiar with basic AR maintenance. Always follow safety protocols.

Tools required

Armorer’s wrench or torque wrench

Torque/ratchet

Step-by-step

Ensure the rifle is unloaded and clear.
Remove existing upper by pushing out the pivot and takedown pins.

Reinsert pivot and takedown pins; torque per manufacturer specs.

Maintenance & Care

Routine maintenance keeps your custom upper running like new.

Cleaning

Disassemble BCG and charging handle; clean carbon and fouling with approved solvent.
Clean barrel bore and chamber with appropriate brushes and patches.
Inspect gas tube, gas block, and extractor for fouling or wear.

Lubrication

Apply high-quality firearm lubricant to the bolt carrier group and contact surfaces per manufacturer recommendations.

Periodic checks

Inspect for loose fasteners, handguard movement, or gas system leaks.
Replace gas rings, extractor springs, or worn components as needed.

Troubleshooting — Common Issues & Fixes

Failure to cycle: Check gas system length, gas block alignment, and proper gas port sizing. Ensure gas key staking and torque are correct.
Extraction/ejection problems: Inspect extractor spring/insert, verify proper headspace, and ensure correct ammunition.
Loose handguard or optics: Re-torque mounting hardware according to spec and use appropriate thread lock where recommended.
