Morning.
Finally getting real rain...
Your reference refers only to the XMP triggers - a relatively new option. The 700 trigger apparently goes back to the original 721 design. That the agreement covers more than just the 700 rifles (including the 600 and derivations thereof) is a new twist to the story.
That said, the deaths and injuries can always be attributed to poor firearm handling and/or ignorance of firearm safety.
