How to Sight in a Rifle Scope

Hunting or legal long-range shooting often requires the proper equipment, which includes the appropriate installation of a rifle scope. The best ar 10 scopes guarantee for accuracy and thus ensuring that you responsibly shoot in the field. For further efficiency in shooting, the sight in of the rifle often needs to be correct and precise as this will also encourage appropriate, quick, and ethical killing.

It is usually not a precision science; however, the process of rifle sight in requires the following of specific crucial steps to ensure that you do not miss your target and unleash the undesired consequences. Thus, some of the steps to be followed to sight in a rifle properly include;

Proper rifle scope mounting

This is the first step in this process, and it also entails a series of mini-steps for properly installing the scope. For instance, first, you need to ensure that you have all the tools needed and that the rifle chamber is clear and the barrel pointed in a safe direction. Then, you may carefully mount the bases and the rings, followed by the aligning of the rifle and the scope to precision using levels.

This step should ensure that your rifle is stationed on a stationary and stable ground and a good resting platform such as the vice. With everything correctly set, you may move to the next step.

This step involves looking down the bore/the barrel for alignment by first removing the bolt to give a clear view through the barrel then point the barrel towards a high contrast target while still in the stationery resting position.

With the target within the desired range and the rifle at rest, you will look directly through the barrel while moving it around the target until you have the center of the target in your sights. This means that the center of the target will be in sync and direct alignment with the center of the bore, then you should tighten the screws on the vice and ensure that the rifle does not move an inch afterward.

Scope reticle focusing

After aligning the barrel to the target center, you will need to align the scope too to the target center. Thus, you will look through the scope and establish the direction and angling of the reticle. The adjustment of the scope will follow this by moving it in terms of windage and elevations until the reticle is also aligned with the dead center of the target earlier viewed through the barrel.

The process in itself is not perfect, and thus after adjusting the scope, you should check back the bore again to see the alignment, and if, in any case, you readjust the barrel, then you will have to readjust the scope and the reticle, and the process continues. This is, therefore, a repetitive process until perfection is achieved. It, therefore, requires patience through several attempts.

Reassembly of the rifle

After achieving a relatively accurate sight in on the gun, you should reinstall the removed bolts and tighten the loosened screws in the rifle.

Test shooting

At this stage, everything is set, and thus you can start shooting although at minimal distances such as 50 yards or so to even perfect the sight in further. This is by making precise and fine-tuning adjustments using the scope’s R, L, and U adjustment labels as is in some models. These fine-tuning adjustments will bring the shot groups closer to the target. Thus, after every adjustment, you should shoot several group rounds to ensure that the adjustments are positively moving into place.

Zeroing the dials out

After all the adjustments and achieving the preferable sight in for your rifle, the scope adjustment dial won’t be at zero. Thus, you will have to read the scope manual on how to turn the dial back to zero measurements without interfering with the fine-tuning of the scope reticle.

You are now ready to start shooting in the field, although at the distance of the bore sighting. Thus, you will always, however, have to adjust the scope to guarantee sight in accuracy when adjusting the shooting distance in the field as per the minute of angle (MOA) increment values.
