 Zenith ZF5. It's a clone and they did a great job. 9mm semi-auto MP5 clone made by Zenith Firearms called the ZF5. Here's a closer look at the ZF5, the American made ZF5. Two-point sling, here it is. It is made by Zenith. And I fire, I grip around like this to grab the handguard. Oversized selector switch, slide it here, rip that mag out and everything. Just hit that and you charge 8.9 inch barrel. And it is a roller delayed blowback system, a three lug flash hider. Push it in there just like that.
