The Remington Model 700 5-R Milspec is a precision rifle built on the standard 700 action with a 5-R rifled barrel that uses a five-groove, rounded-groove rifling pattern to reduce jacket deformation and extend barrel life. Originally developed for military procurement evaluations, the commercial 5-R became the preferred base rifle for custom precision builders throughout the 2000s and 2010s. The 5-R rifling pattern minimizes copper fouling and allows longer strings between cleaning.
