About the M4A4 | Mainframe

The M4A4 | Mainframe was added in September 2018, in The 2018 Nuke Collection. In CS2 it still uses the legacy weapon model.

“More accurate but less damaging than its AK-47 counterpart, the M4A4 is the full-auto assault rifle of choice for CTs. A black and white circuit board pattern has been applied.”
