UPDATE: The Tactical Wire got it wrong. Production was not halted.
Tactical Wire claims that significant problems with the HK416 have been uncovered and production has been halted:

The Tactical Wire has learned from very reliable sources that the US military has encountered significant problems with H&K Model 416s in combat conditions. HK has suspended production pending an internal investigation and inspection of that weapon system.

Very interesting if true. I previously reported that Norwegian soldiers were having problems with their HK416s.

Thanks to Ed Friedman for alerting me to this.
