Here is the basic text, copied from the link that I could open.
SIG SAUER, Inc. has determined that a limited number of rifles in the SIG716 DMR®, SIG516® Carbon Fiber and SIGM400® Predator models are subject to a Safety Warning and Recall Notice. Some models were built with a two-stage SIG SAUER trigger that may have an improperly heat-treated hammer. Over time, this could result in a trigger malfunction creating a significant safety hazard. SIG SAUER is issuing a mandatory recall to replace the hammer and trigger assembly in these specific rifles. This recall does not affect any military or law enforcement rifles or any SIG MCX®/SIG MPX® products.
SIG SAUER will correct any of the affected firearms at no cost to the customer.
The firearms affected by the recall can be identified by the presence of a SIG mark etched into the hammer. See image below.
