The weapon does have attachment points for optics and various accessories on top and on all side of the handguard. However, it could be difficult to ensure that the detachable sight would remain properly aligned with either the gun or the individual shooter. It is possible that the Air Force could include a small, non-magnifying sighting system of some kind in the future that a pilot could attach after reassembling their gun.
The gun features folding front and rear “iron sights” rather than an optic of some kind, which is likely a product of the need to fit inside the 16-by-14-by-3.5-inch dimensions of the aircrew survival kit.
