Daytona Tactical test fires every custom AR-15 upper to verify cycling. However, we cannot guarantee cycling with all .300 Blackout ammunition due to vast differences in the quality of ammunition. Will only warranty cycling with US made ammunition. We can not warranty cycling of the AR Upper with imported, steel cased or reloaded rounds.
