Pancor Jackhammer

Nonetheless, its distinctive aesthetics and futuristic design have made it popular as a weapon in many video games, notably Fallout 2, Max Payne, Project I.G.I and Far Cry.

The firearm weapon utilizes semi automatic and fully automatic action and frequently a source of a Mandela effect, notably on the aspect of the firearm being a cinematic staple of the action series,[1] despite IMFDB has not found credible evidence of the weapon appearing in cinema.

[2] Reportedly, several foreign governments expressed interest in the design and even ordered initial production units once ready for delivery.

Those sent to HP White Labs reportedly had 4 lb (1.8 kg) of material removed with increased stamping instead of casting and a different easier method of reloading.

Thus the sole surviving example is not indicative of what would've been an actual production model and is better considered a tool room prototype.

Several dozen non-functioning examples were made from sheet tin, balsa wood, and clay in order to make working tool prototypes.

[2][3] A toolroom prototype that is in technical firing condition, but is constructed largely with machine screws and requires disassembly to reload, was owned by Movie Gun Services, during which its forearm was replaced with an MP5SD handguard.

[7] Unique to the Jackhammer was the ability to convert a loaded cylinder from the weapon into an anti-personnel device similar to a land mine by the addition of a firing mechanism.
