Factory Issue is a weapon available for all non-Grenadier Pilot primary weapons in Titanfall 2. For assault rifles, SMGs, Shotguns and Light Machine Guns, Factory Issue sights are either Iron Sights or Irondot Sights. For the Kraber-AP Sniper and Longbow-DMR, the factory issue is a medium-zoom scope. The R-101C Carbine's Factory Issue sight is an AOG scope and the D-2 Double Take has a custom Sniper Scope reminiscent of the Irondot Sights.
Factory Issue is the standard attachment applied to all weapons that support it upon unlock.
