Understanding the Mossberg 702 Plinkster 22LR Rear Sight

The Mossberg 702 Plinkster is a popular .22LR rifle known for its affordability and reliability. A crucial part of achieving accuracy with any firearm is a properly adjusted sighting system. The rear sight on the Plinkster allows you to make precise adjustments to compensate for windage (left/right) and elevation (up/down). Understanding how these adjustments work is fundamental to zeroing your rifle.

The Mechanics of the Rear Sight

The rear sight typically consists of two adjustment screws or knobs: one for windage and one for elevation. The windage screw moves the rear sight left or right, while the elevation screw moves it up or down. The direction you need to move the rear sight is *opposite* to the direction you want the bullet’s point of impact to move. For example, if your shots are consistently hitting to the right of your target, you need to move the rear sight to the left. The amount of movement each click or rotation of the screw provides will vary, so it’s essential to check your owner’s manual or test fire to determine the adjustment value.

Evolution of Rifle Sights

Rifle sights have evolved significantly over time, from simple fixed blades to sophisticated adjustable systems and now to optics. The Mossberg 702’s adjustable rear sight represents a balance between simplicity and functionality, allowing shooters to fine-tune their accuracy without the need for expensive aftermarket accessories. The very first firearms didn’t even have sights! The Mossberg 702’s basic, yet effective, rear sight is a testament to reliable design.

Importance of a Properly Adjusted Rear Sight

A properly adjusted rear sight is critical for consistent accuracy. Without it, you’ll be constantly compensating for the rifle’s inherent inaccuracies, leading to frustration and poor results. A well-zeroed rifle inspires confidence and allows you to focus on other important aspects of shooting, such as trigger control and breathing.

Essential Tools and Equipment

Before you begin adjusting your rear sight, gather the necessary tools and equipment. Having everything on hand will make the process smoother and more efficient.

* **Screwdriver:** A small, flat-head screwdriver that fits the adjustment screws on your rear sight is essential. Ensure it’s the correct size to avoid damaging the screws.
* **Shooting Rest or Bipod:** A stable shooting rest or bipod will help you maintain a consistent shooting position and reduce human error. Sandbags can also be used for a stable rest.
* **Targets:** Use paper targets with clearly marked aiming points. These will help you track your shots and identify the necessary adjustments.
* **Ammunition:** Use the same type of ammunition you plan to use regularly. Different ammunition types can have different points of impact.
* **Eye and Ear Protection:** Always wear appropriate eye and ear protection when shooting any firearm.
* **Owner’s Manual:** Consult your Mossberg 702 Plinkster owner’s manual for specific instructions and diagrams related to your rifle’s rear sight.

Step-by-Step Guide to Adjusting the Rear Sight

Follow these steps to accurately adjust the rear sight on your Mossberg 702 Plinkster:

1. **Set Up Your Target:** Place your target at a known distance, such as 25 or 50 yards. Ensure the target is securely mounted and clearly visible.
2. **Establish a Stable Shooting Position:** Use a shooting rest or bipod to stabilize your rifle. Take your time and ensure you have a comfortable and consistent shooting position.
3. **Fire a Test Group:** Fire a group of 3-5 shots at the center of the target. Focus on proper trigger control and breathing techniques.
4. **Analyze Your Shot Group:** Examine the location of your shot group relative to the aiming point. Determine if your shots are consistently high, low, left, or right.
5. **Adjust the Rear Sight:** Use the screwdriver to adjust the rear sight based on your analysis. Remember: move the rear sight in the *opposite* direction you want the point of impact to move.
* **Elevation:** If your shots are low, move the rear sight *up*. If your shots are high, move the rear sight *down*.
* **Windage:** If your shots are to the left, move the rear sight to the *right*. If your shots are to the right, move the rear sight to the *left*.
6. **Fire Another Test Group:** After making your adjustments, fire another group of 3-5 shots at the target.
7. **Repeat as Necessary:** Continue to analyze your shot groups and adjust the rear sight until your shots are consistently hitting the center of the target.

Pro Tip: Adjusting for Ammunition

Different ammunition types can have varying velocities and ballistic characteristics, which can affect your point of impact. Once you’ve zeroed your rifle with a specific type of ammunition, it’s a good idea to test it with other types you might use. Make note of any differences in point of impact and adjust accordingly, or stick to the ammunition you used for zeroing for optimal consistency. Our testing has shown that even slight variations in bullet weight can impact accuracy at longer ranges.

Troubleshooting Common Issues

Even with careful adjustments, you may encounter some common issues. Here are some troubleshooting tips:

* **Rear Sight Won’t Move:** If the rear sight is stuck, try applying a small amount of penetrating oil to the adjustment screws. Be careful not to over-tighten the screws.
* **Inconsistent Shot Groups:** Inconsistent shot groups can be caused by a variety of factors, including poor trigger control, inconsistent shooting position, or loose scope mounts. Ensure your rifle is properly maintained and that you are using consistent shooting techniques.
* **Rear Sight Moves Too Easily:** If the rear sight moves too easily, you may need to tighten the screws that hold it in place. Be careful not to over-tighten them, as this can damage the threads.
* **Extreme Adjustments Needed:** If you need to make extreme adjustments to the rear sight to zero your rifle, there may be an underlying issue with the rifle’s barrel or receiver. Consult a qualified gunsmith for assistance.

Proper maintenance will help ensure your rear sight remains accurate and reliable.

* **Cleaning:** Regularly clean your rear sight with a soft cloth to remove dirt and debris. Avoid using harsh chemicals or solvents, as these can damage the finish.
* **Lubrication:** Apply a small amount of gun oil to the adjustment screws to keep them moving smoothly.
* **Inspection:** Regularly inspect your rear sight for any signs of damage or wear. Replace any worn or damaged parts as needed.
