Are Handgun Scopes Okay for Rifle Use?

The eye relief on a handgun scope is not the same as on a rifle. Using a riflescope on a rifle is the best and safest option.
The eye relief for a pistol scope is at arms length. The eye relief on a riflescope varies from roughly three to five inches so that when the rifle is held properly the scope is a safe distance from your eye. Proper positioning of the riflescope and the rifle is an important factor because of recoil.
Some popular brands of variable powered scopes are: Leupold, Nikon, and Bushnell.
