Bore sighting aligns the optical sight on top of the gun barrel with the axis of your bore. Bore sighting should be the first priority after mounting your scope. This will align the cross-hairs of the scope to the spot where the barrel is pointing at a particular distance. Because of variations in the trajectory of ammunition and other factors the bore-sighted rifle will probably not shoot to the exact spot that the cross-hairs indicate. At Stockers Gun Shop, we can provide bore sighting services that will accurately align your sight with the barrel. Never miss a shot with our professional bore sighting services!
