M4 (M4A4 / M4A1-S):

The M4 refers to the Counter-Strike 2 CT-side rifles: the M4A4 and the M4A1-S. Both are standard assault rifles used for holding angles, retaking sites, and winning mid-range fights, but they differ in magazine size, firing sound, and handling.

Players usually choose between them based on preference and role: the M4A4 offers a larger magazine, while the M4A1-S is suppressed and more discreet. In both cases, the M4 is one of the main rifles that defines Counter-Terrorist weapon economy and rifle rounds.
