There are 2 ways to easily sight-in a rifle. With a laser bore sighter or by shooting. First you'll want to clean your rifle and tighten any loose screws for your sights (Remember, a dirty gun is an inaccurate gun). If you choose to use a laser, just simply adjust the sights and double check. To sight-in a rifle by shooting, you'll want to rest your rifle on a table to ensure your gun has as little movement as possible while you're shooting and adjusting. It also helps to have very little wind. Just aim for a bullseye, take a few shots (3 or more in case of any wind or bad ammunition) and adjust your sights until they're accurate. Repeat a few times to ensure accuracy. If your own a bore laser, I suggest using both of these methods. First sight-in using the laser, then check by firing. Sighting-in an MoA scope is significantly more difficult.
line up the target on the top of the front sight while sighting the front sight through the rear peep sight.
"Sighting in" a rifle is the process of adjusting sights (or telescope) so that the point of aim and the point of impact are the same at a given distance. It should be done when the gun is first acquired, whenever sights have been moved (or removed) and prior to use for hunting, shooting in competition, etc.
