Overview
The Mk 12 Special Purpose Rifle (SPR) is an American-designed semi-automatic rifle primarily used by military and law enforcement units.

Its unique configuration combines a lightweight platform, precision accuracy, and the power of the 5.56×45mm NATO cartridge.

Like any firearm, always ensure the rifle is in the “safe” position when not in use and engage it immediately before loading or discharging rounds.
