Airing on channel 314, its focus is specifically modern punk rock.

Prior to the temporary replacement of the channel for GNR radio, Faction was branded as just Faction and played a mix of hard rock, hip hop, heavy metal along with punk rock.

Faction Punk was previously home to Marky Ramone's Punk rock Blitzkrieg, Tim Armstrong's "Tim Timebomb and Friends", The Voice Boyce Show with Dave "The Voice" Boyce, Do It Yourself Radio, Tony Hawk's Demolition Radio, and hourly FU's (Faction Updates).

It is also one of five alternative rock channels on Sirius XM Radio (the others are Alt Nation, 1st Wave, Lithium and SiriusXMU).

In mid-July 2017, Faction was temporarily replaced by Guns N Roses radio.
