The Grady Repeating Arms M-4 Assault Rifle is a selective fire, bullpup assault rifle designed by Earl Rock and John Grady IV between 1977 and 1985. Currently produced by Grady Repeating Arms, the Grady Repeating Arms M-4 is the standard issue assault rifle for all three branches of the Shenandoahan National Guard, having replaced the aging Redhawk Firearms M-3 Assault Rifle in Shenandoahan service. The Grady M-4 Assault Rifle has been praised by infantrymen for its compact size owing to its bullpupp layout, allowing for it to be easily maneuvered and used in the dense forest environments of the Shenandoahan Commonwealth and for its modular design, allowing the rifle to be adapted to the needs of individual operators.
