TFB Review: Trijicon Credo 1-10x28

Once upon a time, the “low power variable optic” (LPVO) was a 1-4x scope.Then along came the 1-6x, then the 1-8x, and now the 1-10x.A top-end with 10x magnification is hardly “low power,” particularly when that was the standard magnification for USMC sniper rifles for many years.
