Upper Assemblies
Moriarti tends to test fire every custom AR-15 upper assembly to verify cycling. We do not guarantee cycling with all ammunition due to vast differences in the quality of ammunition. We will only warranty cycling with the U.S. made ammunition. We will not warranty cycling with imported, steel cased or reloaded rounds.
