This guide is designed for both novice and experienced shooters seeking to fine-tune their Plinkster.

Understanding the Mossberg 702 Plinkster .22LR Rear Sight

The rear sight on the Mossberg 702 Plinkster is typically a simple, adjustable component designed to allow the shooter to compensate for bullet impact deviations. This adjustment is critical for ensuring that the point of aim aligns with the point of impact. The rear sight is primarily responsible for adjusting the *windage* (horizontal correction) and, in some models, the *elevation* (vertical correction). Understanding how these adjustments work is the first step towards achieving accurate shooting. The basic design has remained relatively consistent over the Plinkster’s production run, though minor variations may exist. Knowing the specific type of rear sight on your rifle is important.

The adjustment mechanism usually involves screws or knobs that, when turned, move the rear sight aperture horizontally or vertically. Each click or rotation of the adjustment mechanism typically corresponds to a specific amount of movement at a given distance (e.g., 1/4 inch at 50 yards). The user manual for your specific model provides precise details about the adjustment values.

Components of the Rear Sight

* **Sight Base:** The foundation of the rear sight, usually attached to the receiver of the rifle.
* **Aperture:** The opening through which the shooter aligns the front sight and target. It can be a simple notch or a more refined peep sight.
* **Adjustment Screws/Knobs:** The mechanisms used to move the aperture for windage and elevation corrections.
* **Reference Marks:** Graduations or markings on the sight base that indicate the amount of adjustment.

Why Rear Sight Adjustment Matters

Proper rear sight adjustment is paramount for several reasons:

* **Accuracy:** It ensures that your shots land where you intend them to.
* **Consistency:** Once properly sighted, the rifle will consistently shoot to the same point of impact under similar conditions.
* **Confidence:** Knowing that your rifle is accurately sighted instills confidence in your shooting ability.
* **Ethical Hunting:** In hunting scenarios, accurate sighting is crucial for making clean, ethical shots.

Step-by-Step Guide: Adjusting the Mossberg 702 Plinkster Rear Sight

This section provides a detailed, step-by-step guide to adjusting the rear sight on your Mossberg 702 Plinkster .22LR. Before beginning, ensure the firearm is unloaded and pointed in a safe direction. Always follow safe gun handling practices.

Step 1: Gather Your Supplies

* Mossberg 702 Plinkster .22LR rifle
* Appropriate ammunition
* Screwdriver (if required for adjustment)
* Shooting rest or sandbags (for stability)
* Target
* Eye and ear protection
* User manual (for specific adjustment values)

Step 2: Set Up Your Target

Place your target at a known distance (e.g., 25 yards, 50 yards). A well-defined target with clear aiming points is essential.

Step 3: Establish a Stable Shooting Position

Use a shooting rest or sandbags to stabilize the rifle. A stable platform is crucial for consistent results during sighting.

Step 4: Fire a Group of Shots

Fire a group of 3-5 shots at the target. Aim carefully at the center of the target each time. Analyze the shot group to determine the necessary adjustments.

Step 5: Analyze the Shot Group

* **Windage Adjustment:** If the shot group is consistently to the left of the target center, you need to move the rear sight to the right. If the shot group is to the right, move the rear sight to the left.
* **Elevation Adjustment:** If the shot group is consistently high, you need to lower the rear sight. If the shot group is low, raise the rear sight.

Step 6: Make the Adjustments

Using the adjustment screws or knobs, carefully adjust the rear sight according to the analysis in Step 5. Refer to your user manual for the specific adjustment values (e.g., one click equals 1/4 inch at 50 yards).

Step 7: Fire Another Group of Shots

After making the adjustments, fire another group of 3-5 shots at the target. Analyze the new shot group to see if further adjustments are needed.

Step 8: Repeat as Necessary

Repeat steps 5-7 until your shot group is consistently centered on the target. Be patient and make small adjustments each time. It may take several iterations to achieve perfect sighting.

Troubleshooting Common Rear Sight Adjustment Issues

Even with careful adjustment, you may encounter some common issues. Here’s how to troubleshoot them:

* **Sight is Bottomed Out:** If you’ve reached the limit of the adjustment range and the point of impact is still off, you may need to consider shimming the front or rear sight base.
* **Loose or Wobbly Sight:** A loose sight will not hold its adjustment. Tighten any screws or fasteners that secure the sight to the receiver. If the sight is damaged, consider replacing it.
* **Inconsistent Shot Groups:** Inconsistent shot groups can be caused by a variety of factors, including poor shooting technique, inconsistent ammunition, or a damaged barrel. Eliminate these factors before blaming the sight.
* **Difficulty Seeing the Sights:** If you have difficulty seeing the sights, consider using a higher contrast target or adjusting the lighting.

Upgrading Your Mossberg 702 Plinkster Sights

While the stock sights on the Mossberg 702 Plinkster are functional, many shooters choose to upgrade them for improved visibility and accuracy. Several aftermarket sight options are available, including:

* **Fiber Optic Sights:** These sights use fiber optic inserts to provide bright, highly visible aiming points, especially in low-light conditions. Brands like HiViz offer compatible options.
* **Peep Sights:** Peep sights offer a more precise sight picture than traditional notch sights. They typically consist of a small aperture at the rear and a front post or bead.
* **Red Dot Sights:** A red dot sight offers quick target acquisition and improved accuracy, especially for close-range shooting. Mounts are available to attach red dot sights to the Plinkster.

Upgrading to better *aftermarket sights* can significantly enhance the shooting experience and improve accuracy.

The Importance of Ammunition Choice

Ammunition choice can significantly impact the accuracy of your Mossberg 702 Plinkster. Different brands and types of .22LR ammunition can have varying velocities and ballistic characteristics. It’s essential to find ammunition that your rifle shoots accurately and consistently. Experiment with different brands and bullet weights to determine which performs best in your Plinkster. *Consistent ammunition* is key to achieving accurate sighting.

Maintaining Your Mossberg 702 Plinkster

Proper maintenance is crucial for ensuring the reliability and accuracy of your Mossberg 702 Plinkster. Regularly clean and lubricate the rifle to prevent corrosion and ensure smooth operation. Pay particular attention to the barrel, bolt, and trigger mechanism. A clean rifle is a happy and accurate rifle.

* **Cleaning the Barrel:** Use a bore brush and solvent to remove fouling from the barrel. A clean barrel is essential for accuracy.
* **Lubricating Moving Parts:** Apply a light coat of oil to the bolt, trigger mechanism, and other moving parts to ensure smooth operation.
* **Inspecting the Sights:** Regularly inspect the sights for damage or looseness. Tighten any screws or fasteners as needed.

Advantages of a Properly Adjusted Rear Sight

Having a properly adjusted rear sight on your Mossberg 702 Plinkster offers numerous advantages:

* **Enhanced Accuracy:** Allows you to consistently hit your target.
