Understanding the Mossberg 702 Plinkster .22LR Rear Sight

The rear sight on the Mossberg 702 Plinkster .22LR is a crucial component for achieving accurate shots. It’s designed to be adjustable for both windage (horizontal correction) and elevation (vertical correction). Understanding how these adjustments work is paramount to zeroing your rifle correctly.

* **Windage:** This refers to the left-right adjustment of the rear sight. Adjusting windage corrects for shots that consistently land to the left or right of your target.
* **Elevation:** This refers to the up-down adjustment of the rear sight. Adjusting elevation corrects for shots that consistently land high or low of your target.

The factory rear sight on the 702 Plinkster is typically a simple, yet effective, design. It usually consists of a notched piece of metal that can be moved laterally (for windage) and vertically (for elevation) using small screws or other adjustment mechanisms. The exact design can vary slightly depending on the year of manufacture, but the basic principles remain the same.

The Importance of Proper Sight Adjustment

A properly adjusted rear sight is the foundation of accurate shooting. Without it, you’ll be constantly compensating for the rifle’s inherent inaccuracy, leading to frustration and poor results. A well-zeroed rifle allows you to focus on your shooting technique, improving your consistency and overall enjoyment of the sport. Furthermore, failing to adjust your sights can lead to inaccurate groupings, which is crucial in competitive shooting or hunting scenarios. Many users report improved groupings of up to 50% after properly adjusting their rear sights.

Tools You’ll Need

Before you begin, gather the necessary tools. Having the right tools on hand will make the process much smoother and prevent damage to your rifle.

* **Small Screwdriver Set:** A set of small, high-quality screwdrivers is essential for adjusting the windage and elevation screws. Ensure the screwdrivers fit the screws perfectly to avoid stripping them.
* **Shooting Rest or Sandbags:** A stable shooting rest or sandbags will help you maintain a consistent shooting position, which is crucial for accurate sight adjustment.
* **Targets:** Use paper targets with clearly marked bullseyes. Different target sizes and distances can be used depending on your experience level and the type of shooting you’re doing.
* **Ammunition:** Use the same type of ammunition you typically use for shooting. Different types of ammunition can have different points of impact, so consistency is key.
* **Eye and Ear Protection:** Always wear eye and ear protection when shooting. Safety is paramount.
* **Cleaning Supplies (Optional):** While not strictly necessary for sight adjustment, having cleaning supplies on hand is always a good idea to keep your rifle in top condition.

Step-by-Step Guide to Adjusting the Rear Sight

Now, let’s get to the heart of the matter: adjusting the rear sight. Follow these steps carefully to ensure accurate results.

1. **Set Up Your Shooting Position:** Place your rifle on the shooting rest or sandbags, ensuring it’s stable and level. Aim at the center of your target.
2. **Fire a Test Group:** Fire a group of 3-5 shots at the target. This will give you an idea of where your shots are landing in relation to the bullseye. Analyze the group to determine the necessary adjustments.
3. **Assess the Impact:** Examine your target. Are your shots consistently high, low, left, or right of the bullseye? This will determine which adjustments you need to make.
4. **Adjusting Windage:**
* If your shots are landing to the *left* of the bullseye, you need to move the rear sight to the *right*.
* If your shots are landing to the *right* of the bullseye, you need to move the rear sight to the *left*.
* Use your small screwdriver to carefully adjust the windage screw in the appropriate direction. Make small adjustments, as even a slight movement can have a significant impact on your point of impact.
5. **Adjusting Elevation:**
* If your shots are landing *low* of the bullseye, you need to raise the rear sight.
* If your shots are landing *high* of the bullseye, you need to lower the rear sight.
* Use your small screwdriver to carefully adjust the elevation screw in the appropriate direction. Again, make small adjustments.
6. **Fire Another Test Group:** After making your adjustments, fire another group of 3-5 shots at the target. This will allow you to see if your adjustments have had the desired effect.
7. **Repeat as Necessary:** Repeat steps 3-6 until your shots are consistently landing in or near the bullseye. This may take several iterations, so be patient and methodical.

Troubleshooting Common Issues

Even with careful attention to detail, you may encounter some common issues during the sight adjustment process. Here are a few troubleshooting tips:

* **Screws are Stripped:** If the screws are stripped, you may need to replace them. Contact Mossberg or a gunsmith for replacement parts.
* **Sight is Loose:** If the sight is loose, tighten the screws that hold it in place. If the screws are already tight, the sight may be damaged and need to be replaced.
* **Inconsistent Shots:** If your shots are inconsistent, even after adjusting the sight, there may be other factors at play, such as poor shooting technique, inconsistent ammunition, or a damaged barrel. Try using a different type of ammunition or consult with a gunsmith.
* **Extreme Adjustments Required:** If you need to make extreme adjustments to the sight to achieve zero, there may be a problem with the rifle itself. Consult with a gunsmith to diagnose and repair the issue.

Understanding MOA and Sight Adjustments

MOA, or Minute of Angle, is a unit of angular measurement commonly used in firearms. Understanding MOA can help you make more precise sight adjustments. One MOA is approximately equal to one inch at 100 yards. This means that if your shots are one inch low at 100 yards, you need to adjust your sight by one MOA.

The exact MOA value of each click on your Mossberg 702 Plinkster’s rear sight may vary depending on the model and year of manufacture. Consult your owner’s manual or contact Mossberg for specific information.

Upgrading Your Mossberg 702 Plinkster Sights

While the factory sights on the Mossberg 702 Plinkster are adequate for basic shooting, upgrading to aftermarket sights can significantly improve your accuracy and shooting experience. Several aftermarket sight options are available, including:

* **Fiber Optic Sights:** These sights use fiber optic rods to gather light, making them brighter and easier to see in low-light conditions.
* **Ghost Ring Sights:** These sights feature a large rear aperture, which allows for faster target acquisition.
* **Peep Sights:** Peep sights offer a more precise aiming point than traditional notch sights.

Installing Aftermarket Sights

Installing aftermarket sights typically involves removing the factory sights and replacing them with the new sights. The process can vary depending on the type of sights you’re installing. Some sights may require gunsmithing services, while others can be installed at home with basic tools. Always consult the manufacturer’s instructions before installing aftermarket sights.

Maintaining Your Mossberg 702 Plinkster Rear Sight

Proper maintenance of your rear sight is essential for ensuring its accuracy and longevity. Here are a few tips:

* **Keep it Clean:** Regularly clean your rear sight with a soft cloth to remove dirt, debris, and powder residue.
* **Lubricate Moving Parts:** Lubricate the windage and elevation screws with a small amount of gun oil to keep them moving smoothly.
* **Protect from Damage:** Avoid dropping or bumping your rifle, as this can damage the rear sight.
* **Store Properly:** Store your rifle in a safe and dry place to prevent rust and corrosion.
