*****Ammunition Notification***** Ghost Firearms test fires every custom upper 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 US made ammunition. We will not warranty cycling with imported, steel cased or reloaded rounds.
All NFA and local laws apply, make sure you know them before ordering or installing this upper.
allow 3-4 business days to build and test fire all built uppers
