The scopes in this category are extremely suited for lighter weight bolt guns and semi auto precision system. They work very well at ranges of 0-1000 yards on practical sized targets. High end magnification will be 18 power. Selections of First Focal Plane (FFP) Second Focal Plane (SFP) and different style reticle's are all choices to be made. When in doubt call the pro's at Oakland Tactical for consultation.
