In the early years of the GWOT, PRI’s Mk12 SPR was designed to fill the role between M4 carbines and SR25 sniper systems. Heralded for reliability and accuracy in some of the most demanding environments on earth, the Mk12 earned its place in the SOCOM arsenal. Because they were building for extreme precision, PRI became known for their standards of quality for receiver sets.
