Open Sights—With the traditional open sight often found on sporting rifles and on “buck special” or “riot” shotguns, find the front sight first and then pull the front sight into the rear sight notch. Open sights are not as good as aperture sights for quick action but, with some practice, a skilled shooter can make them work.
Optical Sights—Any agency or individual officer thinking of fitting a patrol carbine with optical sights should step back for a second and weigh the pros and cons of these devices. A modern rifle scope has many benefits but, contrary to popular belief, it will not automatically make you a better shot.
As police officers and 21st century Americans, we have a great love for gadgets, and the optical sight is a great gadget. However, it has some drawbacks in a patrol environment. First of all, it can easily be damaged in the trunk of a cruiser. Second, you need to make sure that your batteries are fresh. You don’t want to get into a fight with an inoperable scope. Finally, shooting well with a scope requires a lot of practice. Be sure that you want to put in that time before you invest in one.
There are, of course, many advantages to an optical sight. In addition to the magnification that it provides, an optical sight is on a single plane, meaning there is no front and rear sight, only the sight reticle. As a result, it is much easier to focus on the target.
While we’re at it, let’s discuss magnification for a moment. Remember, a patrol carbine is not intended for the same kind of duty as a sniper rifle. That’s why, for general issue, I suggest an optical sight with the lowest magnification, from no magnification to perhaps four power. Field of view is an issue, especially when you consider that you may have to use your patrol rifle at anywhere from point-blank range to more than 100 yards.
