Understanding Open Sight Components
The Front Sight
The front sight, typically located near the muzzle, is what your eye will focus on predominantly. Its primary role is to provide a point of reference for aiming. Front sights come in various forms, each with its unique advantages. Common types include: Bead sights, Post sights, and Hooded sights.
The Rear Sight
The rear sight, typically positioned closer to the shooter’s eye, serves as the secondary point of reference. It provides a frame of reference for the front sight, enabling a consistent line of sight. This alignment is crucial for accuracy. The rear sight also often houses the adjustment mechanisms that permit you to correct where your bullet impacts. The rear sight also has different types, including Notch sights and Aperture sights. The ability to fine-tune the rear sight’s position is fundamental for accurate shooting. This is where elevation and windage adjustments come into play. Elevation adjustments allow you to move the point of impact (POI) of your bullets up or down. Windage adjustments permit you to shift the POI left or right.
The Fundamentals of Sight Alignment and Sight Picture
Sight Alignment
Sight alignment involves precisely positioning the front sight within the rear sight’s frame. For instance, with a notch and post system, the goal is to center the front sight post vertically and horizontally within the notch. The top of the front sight post should be level with the top of the rear sight, forming a straight horizontal line. Any deviation from this, such as canting the rifle or inconsistent alignment, will translate into inaccuracies downrange. Maintaining consistent alignment is key to producing consistent groups. Proper practice helps develop the muscle memory required for instinctive sight alignment.
Sight Picture
The sight picture incorporates the correct sight alignment while simultaneously considering the target’s position in relation to the sights. The correct sight picture involves focusing on the front sight, with the target appearing somewhat blurred in the background. The correct sight picture requires you to hold the sights in alignment, and place the front sight precisely where you want the shot to hit. In most cases, you’ll want to place the top of the front sight at the desired point of impact. Consistency in sight picture, just like in sight alignment, is paramount. Developing a consistent sight picture means holding your sights and the target in the exact same relationship every time you shoot. The sight picture directly influences where your shot goes.
Zeroing Your Rifle
Preparation
Always adhere to all gun safety rules. This includes treating every firearm as if it were loaded, keeping the muzzle pointed in a safe direction, and keeping your finger off the trigger until ready to shoot. Gather your rifle, ammunition, shooting target, shooting rest or a stable position, and any tools necessary for adjusting your sights. Establish a stable shooting position. This could be using a bench rest, sandbags, or a prone position. This will minimize movement and ensure consistency.
Initial Shots
Start with a reasonable distance. This is typically 25 yards or 50 meters. This distance helps you make more obvious adjustments with fewer rounds. Fire a small group of shots (e.g., three to five) at the target. Assess the group of shots and identify their collective center. This is the initial point of impact.
Making Adjustments
Windage Adjustment
Determine if the center of your group is left or right of your point of aim. If your shots are hitting to the left, you typically need to move the rear sight to the right to counter that (and vice versa). Observe the distance between the point of impact and your desired point of aim. Make the necessary windage adjustments using the mechanisms on your rear sight. Refer to the manufacturer’s instructions or the click value of your sights.
Elevation Adjustment
Determine if your shots are impacting high or low. If the shots are low, raise the rear sight. If the shots are high, lower the rear sight. Determine the distance between the point of impact and your point of aim. Utilize the elevation adjustment on your rear sight and make the corrections. Understand the value of each click on your sights. One click represents a small amount of change.
Test and Refine
Fire a new group of shots after making any sight adjustments. Observe the new point of impact. Repeat the adjustment process as needed until the point of impact aligns with your desired point of aim. Consider moving your target further away for more accurate zeroing at long distances.
Troubleshooting Common Problems
Inconsistent Grouping
Inconsistent grouping can be caused by several factors: Shooter Error, Amuunition, Rifle Issues, and Environmental Factors.
Sight Issues
Loose sights, bent sights and faded sights can all compromise accuracy. Secure loose sights with the appropriate tools. Inspect sights for any bending, which can compromise the accuracy. If the sights are faded, consider replacing or painting them.
Advanced Techniques and Considerations
Understanding Ballistics
Understand how gravity affects your bullets at longer distances. Use ballistics calculators to help account for drop and wind drift.
Shooting in Different Conditions
Learn to estimate wind speed and direction and adjust your aim accordingly. Lighting affects sight picture, so it is important to understand where to place your sights in different lighting conditions.
Maintenance and Care
Cleaning
Regularly clean the sights with a soft cloth and a suitable gun cleaning solvent to remove dirt and debris.
Inspection
Regularly inspect the sights for any signs of damage, wear, or looseness.
Storage
Store your rifle in a safe and secure location, protecting it from the elements.
