New in 2018: Corps adopts M855A1 round | Marine Corps Times

In 2018 the Marine Corps will be adopting the Army’s enhanced 5.56mm rifle round for Marines in combat.

The Army’s M855A1 round has proved a deadlier bullet than the Corps’ M855 5.56mm round, said Chris Woodburn of the Corps’ Combat Development Command.

“The M855A1 provides improved performance over the current M855, 5.56mm round in a lead-free form factor, and provides improved steel penetration, hard- and soft-target terminal effects, with more consistent terminal effects than the M855 at ranges out to 600 meters,” Woodburn told Marine Corps Times.

The Marine Corps will begin ­procuring the enhanced round for its combat stockpiles this fiscal year, said ­Woodburn. ­Deployed Marines who are ­issued M855A1 rounds can use them now.
