The Driller Machine Gun is a Machine Gun in Far Cry 4 that can be unlocked through U-Play Pre-Order. This weapon appears to be a variant on the PKM machine gun which appeared in Far Cry 3 and may be based on the real life PKP Pecheneg, a modernized variant of the PKM used by Russian Spetsnaz special forces. It has an optical sight, an extended magazine of 200 rounds, a custom paint job and penetrating rounds that have a capability of punching trough walls like the SA-50's.
