CS2 players use the M4A1-S as an alternative to the M4A4.The silencer of the M4A1-S removes bullet traces while shooting through smoke, which makes you less detectable. The accuracy of this rifle is slightly higher. But the M4A1-S has ten rounds less in the magazine, and costs more. The CT’s primary assault rifle should be chosen before matches, as the M4A4 and M4A1-S share one slot. The silencer opens more artistic opportunities for the M4A1-S skins, making them some of the most beautiful items in CS2.
