Understanding the Mossberg 702 Plinkster .22LR Rear Sight: A Deep Dive
The Mossberg 702 Plinkster .22LR is a popular choice for recreational shooting, small game hunting, and training due to its affordability, lightweight design, and ease of use. However, like any firearm, achieving accuracy requires understanding its components, particularly the sights. The rear sight on the 702 Plinkster is typically a simple, adjustable notch sight, designed to allow the shooter to compensate for bullet drop and windage (horizontal deviation). This adjustability is crucial, as ammunition variations, shooting distances, and environmental conditions all influence where a bullet impacts the target.
Historically, simple notch sights have been used on firearms for centuries. The design prioritizes simplicity and durability. The 702 Plinkster’s rear sight continues this tradition, offering a robust and relatively easy-to-adjust system. While not as precise as more advanced optical sights, the factory iron sights are perfectly adequate for plinking and small game hunting at reasonable distances.
Understanding the underlying principles of ballistics is key to effectively using the rear sight. Gravity causes bullets to drop as they travel downrange, and wind can push them off course. The rear sight adjustments allow you to compensate for these factors. Elevating the rear sight will cause the point of impact to rise, while moving it laterally will shift the impact left or right. Small adjustments can make a significant difference at longer ranges.
The current relevance of mastering iron sights is often overlooked in an era of readily available optics. However, learning to shoot accurately with iron sights builds fundamental marksmanship skills, provides a reliable backup sighting system in case of optic failure, and allows for a deeper connection with the firearm. Furthermore, many shooting competitions still require or encourage the use of iron sights, rewarding skill and precision.
The Role of the Rear Sight in Achieving Accuracy
The rear sight works in conjunction with the front sight to create a sight picture. This sight picture is the alignment of the front sight post within the rear sight notch, with the target superimposed on top. The goal is to consistently align these three elements – rear sight, front sight, and target – for each shot. Any variation in this alignment will result in inaccuracies.
Think of the rear sight as the anchor point for your eye. It provides a reference point for aligning the front sight. By adjusting the rear sight, you are essentially changing the angle at which the bullet leaves the barrel, compensating for external factors like gravity and wind. The closer you can get to perfect alignment, the more accurate your shots will be.
The Bushnell Iron Sight Laser Bore Sighter is a tool that can help in quickly achieving accuracy. It works by projecting a laser beam down the barrel of your firearm, allowing you to align your iron sights with the laser dot on a target. This process provides a visual reference for adjusting the sights, significantly reducing the time and ammunition required to zero in your rifle. By using the bore sighter, you can make initial adjustments to the rear sight before even firing a shot, saving you time and frustration at the range.
Detailed Features Analysis of the Mossberg 702 Plinkster Rear Sight
Let’s break down the key features of the Mossberg 702 Plinkster’s rear sight:
1. **Adjustable Elevation:** Most 702 Plinkster rear sights offer elevation adjustment, typically achieved by moving the rear sight blade up or down. This compensates for bullet drop at different distances. How it works: A small screw or ramp mechanism allows you to raise or lower the sight blade. The user benefit is the ability to accurately engage targets at varying ranges without having to hold over or under.
2. **Adjustable Windage:** Windage adjustment allows you to correct for horizontal deviations caused by wind or inherent inaccuracies in the rifle or ammunition. How it works: Usually, a screw or similar mechanism allows you to move the rear sight blade left or right within its housing. The user benefit is the ability to compensate for wind drift and achieve accurate shots even in windy conditions.
3. **Durable Construction:** The rear sight is typically made from steel or a durable polymer, designed to withstand the rigors of regular use and exposure to the elements. How it works: The materials are chosen for their strength and resistance to corrosion. The user benefit is a reliable sighting system that will hold its zero and function properly for years to come.
4. **Simple Design:** The simplicity of the rear sight makes it easy to understand and adjust, even for novice shooters. How it works: The design minimizes the number of moving parts and complex mechanisms. The user benefit is a user-friendly sighting system that requires minimal maintenance and is less prone to malfunction.
5. **Secure Mounting:** The rear sight is securely mounted to the receiver of the rifle, ensuring it remains stable and holds its zero. How it works: The sight is typically attached using screws or a dovetail mount. The user benefit is a stable and reliable sighting system that will not shift or move under recoil.
6. **Clear Sight Picture:** The rear sight notch is designed to provide a clear and unobstructed view of the front sight and the target. How it works: The notch is typically wide enough to allow for easy acquisition of the front sight, but narrow enough to provide a precise aiming point. The user benefit is a comfortable and accurate sighting experience.
7. **Aftermarket Upgrades:** While the factory rear sight is functional, several aftermarket options are available, offering improved adjustability, visibility, or durability. How it works: These upgrades often feature finer adjustment increments, brighter fiber optic inserts, or more robust construction. The user benefit is the ability to customize the sighting system to their specific needs and preferences.
Advantages, Benefits, & Real-World Value of Properly Adjusted Rear Sight

Insightful Q&A Section
Here are 10 frequently asked questions about adjusting the rear sight on a Mossberg 702 Plinkster .22LR:
1. **Q: How do I know if my rear sight needs adjustment?**
A: If your shots are consistently landing high, low, left, or right of your intended target, even after accounting for wind and distance, your rear sight likely needs adjustment.
2. **Q: What tools do I need to adjust the rear sight?**
A: Typically, a small screwdriver or Allen wrench is required, depending on the specific design of your rear sight. Consult your owner’s manual for the correct tool.
3. **Q: How do I adjust the elevation of the rear sight?**
A: Locate the elevation adjustment screw or ramp on the rear sight. Turning the screw clockwise will typically lower the point of impact, while turning it counter-clockwise will raise it. Make small adjustments and test your results.
4. **Q: How do I adjust the windage of the rear sight?**
A: Locate the windage adjustment screw on the rear sight. Turning the screw in one direction will move the point of impact to the left, while turning it in the opposite direction will move it to the right. Again, make small adjustments and test your results.
5. **Q: How much should I adjust the sight at a time?**
A: Start with small adjustments, such as 1/4 or 1/2 turns of the adjustment screw. It’s better to make multiple small adjustments than one large adjustment that overcorrects the problem.
6. **Q: How far away should I be when sighting in my rifle?**
A: A good starting point is 25 yards. This distance is close enough to allow you to easily see your point of impact, but far enough to give the bullet time to stabilize.
7. **Q: What is the best way to support the rifle while sighting in?**
A: Use a stable rest, such as sandbags or a shooting vice, to minimize movement and ensure consistent results. This will help you isolate the accuracy of the rifle and sights from your own shooting technique.
8. **Q: How do I compensate for wind while sighting in?**
A: If there is a consistent wind, aim slightly into the wind to compensate for its effect on the bullet. The amount of compensation required will depend on the wind speed and the distance to the target.
9. **Q: What if I run out of adjustment on the rear sight?**
A: If you run out of adjustment on the rear sight, you may need to consider using different ammunition or adjusting the front sight. Consult a gunsmith for assistance if needed.
10. **Q: How often should I check the zero of my rifle?**
A: It’s a good practice to check the zero of your rifle before each shooting session, especially if you’ve transported it or if it’s been subjected to any impacts. This will ensure that your sights are still properly aligned.
