The U.S. Marine Corps has officially adopted the M4 carbine to replace the M16.
Many Marines already have the M4, which has been issued to the select members of the service for about a decade.
The weapon’s shorter barrel, compact size and lighter weight make it ideal in tight quarters such as urban operations.
As my colleague, Matthew Cox has reported, officials this summer signaled their intentions to finally switch out the M16A4, in part because of the M4’s improved accuracy using new 5.56mm rounds.
The transition is expected to be complete by the Sept. 30 end of fiscal 2016.
