Understanding the Mossberg 702 Plinkster and Its Rear Sight
The Mossberg 702 Plinkster is a widely popular, affordable, and reliable .22LR rifle known for its lightweight design and ease of use. It’s a favorite among recreational shooters, beginners, and those looking for a fun and inexpensive plinking rifle. A key component of its accuracy is the adjustable rear sight. The ability to fine-tune this sight is crucial for achieving consistent hits, especially at varying distances. Understanding the mechanics of the rear sight and how it interacts with the front sight is the first step towards mastering your rifle’s accuracy. Many owners find that the factory settings are not optimal for their shooting style or preferred ammunition, making adjustments necessary.
The Importance of Rear Sight Adjustment
A properly adjusted rear sight ensures that your point of aim aligns with your point of impact. When your shots consistently land to the left, right, high, or low of your target, it’s a clear indication that your rear sight needs adjustment. Neglecting to make these adjustments can lead to frustration, wasted ammunition, and ultimately, a less enjoyable shooting experience. Moreover, environmental factors like wind and distance can significantly impact bullet trajectory, necessitating further sight adjustments for optimal accuracy.
Components of the Rear Sight
The rear sight of the Mossberg 702 Plinkster typically consists of two primary adjustment mechanisms: windage and elevation. Windage refers to the horizontal adjustment (left and right), while elevation refers to the vertical adjustment (up and down). Each click or increment of adjustment on these mechanisms corresponds to a specific change in the point of impact at a given distance. Understanding the relationship between these adjustments and their impact on accuracy is paramount for effective sight correction.
Step-by-Step Guide to Adjusting the Rear Sight on Your Mossberg 702 Plinkster
Adjusting the rear sight on your Mossberg 702 Plinkster is a straightforward process, but it requires patience and attention to detail. Follow these steps for optimal results:
- Gather Your Tools and Materials: You’ll need a small screwdriver or sight adjustment tool (often a small flathead screwdriver will work), your Mossberg 702 Plinkster rifle, ammunition, a target, and eye and ear protection.
- Set Up Your Shooting Range: Choose a safe and controlled environment with a clear backstop. Place your target at a known distance (e.g., 25 yards).
- Establish a Stable Shooting Position: Use a bench rest or sandbags to ensure a stable and consistent shooting platform. This minimizes shooter error and allows for accurate assessment of your rifle’s accuracy.
- Fire a Test Group: Fire a group of 3-5 shots at the target. Observe the grouping of your shots. Are they consistently to the left, right, high, or low of the bullseye?
- Adjust Windage: If your shots are consistently to the left, move the rear sight to the right. If your shots are consistently to the right, move the rear sight to the left. Make small adjustments (e.g., one or two clicks) at a time. Remember, “FORS” – Front Opposite, Rear Same. If the group is to the Right, move the Rear sight to the Right.
- Adjust Elevation: If your shots are consistently low, raise the rear sight. If your shots are consistently high, lower the rear sight. Again, make small adjustments at a time.
- Fire Another Test Group: After making adjustments, fire another group of 3-5 shots at the target. Observe the grouping and compare it to your previous group.
- Repeat the Process: Continue adjusting windage and elevation as needed until your shots are consistently hitting the bullseye.
Tips for Precise Adjustments
* Make Small Adjustments: Avoid making large adjustments, as this can lead to overcorrection and further inaccuracies. Small, incremental adjustments are key to achieving pinpoint accuracy.
* Take Your Time: Adjusting your rear sight is not a race. Take your time, focus on your shooting technique, and carefully assess your results after each adjustment.
* Consider Ammunition: Different types of ammunition can have different points of impact. If you switch to a different brand or type of ammunition, you may need to re-adjust your rear sight.
* Environmental Factors: Wind and other environmental factors can affect bullet trajectory. Be mindful of these factors when making adjustments.
Troubleshooting Common Issues with the Mossberg 702 Plinkster Rear Sight
Even with careful adjustments, you may encounter some common issues with the Mossberg 702 Plinkster rear sight. Here are some troubleshooting tips:
* Rear Sight Won’t Move: If the rear sight is stuck or difficult to move, try applying a small amount of lubricant (e.g., gun oil) to the adjustment screws. Be careful not to over-tighten the screws.
* Rear Sight Moves Too Easily: If the rear sight moves too easily and won’t hold its position, the adjustment screws may be loose. Try tightening the screws slightly.
* Inconsistent Groupings: If your shots are still inconsistent after making adjustments, check your shooting technique, ammunition, and the condition of your rifle. A loose barrel or damaged crown can also affect accuracy.
* Rear Sight is Damaged: If the rear sight is physically damaged, it may need to be replaced. Contact Mossberg or a reputable gunsmith for replacement parts.
