The Nighthawk PDW is designed for using our own developed proprietary caseless 5.56mm cartridge, making this a powerful weapon in a compact package. The ejection port is only used when making sure the gun is safe or clearing a dud round. (which obviously won't happen, ever.)
Integrated in the handguard is a battery compartment to provide power to both the flashlight under the barrel and the laser aiming module located above the barrel. On the side of the handguard is a battery life indicator. Rotate the flashlight 90° to the right to turn it on.
The handguard does allow for suppressor use, but the flashlight has to be taken out to make room for it. However, the Nighthawk has plenty of rail space to add a flashlight somewhere else.
