While the changes are not as dramatic as those from last year's symposium, they mark a continuation of the Corps' drive toward greater efficiency and lethality under the "every Marine a rifleman" mentality.
Here's a look at the most-notable changes.

"It's sad to see the iron sights go," he said. "The Marine Corps takes marksmanship seriously. If you need [the micro iron sights], you need them; just flip them up and you're good to go."
The two-point sling allows greater flexibility to shooters, doubling as a firing aid and carrying strap, said Lamb, who supplies them to Marine Corps Forces Special Operations Command via his company.
"It's something the services have needed to do across the board for years," he said. "The three-point sling doesn't have any ability against the body, to tighten while wearing or shooting prone."

Details have yet to be announced but if adopted, it would follow sweeping changes made to Marines' rifle marksmanship training tables over the last year.
