The Rock River Arms (RRA) reputation for quality firearms extends to their selection of rear sights. Whether you're a seasoned marksman or a new shooter, understanding your rear sight is crucial for accurate shooting. This guide dives deep into RRA rear sights, covering their types, features, adjustments, and troubleshooting.
Understanding Rock River Arms Rear Sight Options
Rock River Arms offers a variety of rear sights compatible with their AR-15 platform rifles. These generally fall into two main categories:
1. A2-Style Rear Sights: The Classic Choice
The A2-style rear sight is a classic, reliable, and readily available option. Its robust construction and simple design make it a favorite among many AR-15 owners. Key features include:
- Aperture Design: The A2 sight utilizes an aperture (peep sight) for aiming, offering a clear sight picture. This is generally preferred in low-light conditions compared to some other styles.
- Windage and Elevation Adjustments: These sights are easily adjustable for windage (left/right) and elevation (up/down), allowing for precise zeroing at your chosen range. The adjustment process is usually straightforward, involving small increments via a screw.
- Durability: Built from steel, these sights are known for their resilience and ability to withstand the rigors of regular use and potential impacts.
- Ambidextrous Operation: The design allows for easy manipulation from either side of the weapon.
2. Low-Profile Rear Sights: For Enhanced Optics Compatibility
For shooters using optics (scopes, red dots), low-profile rear sights are an excellent choice. They sit lower to the receiver, minimizing interference with the optic when not in use.
- Co-witnessing Capability: Many low-profile sights are designed for "co-witnessing," meaning they allow you to see both the iron sights and the optic simultaneously. This provides a backup aiming system if your optic malfunctions.
- Folding Mechanisms: Some low-profile rear sights feature folding mechanisms, keeping them out of the way when not needed and reducing the risk of snagging.
- Material Variation: Low-profile sights can be found in various materials, including aluminum and steel, influencing their durability and weight.
Adjusting Your Rock River Arms Rear Sight
Properly adjusting your rear sight is vital for accurate shooting. While the specific process may vary slightly depending on the model, the general principles remain the same:
1. Zeroing Your Rifle: A Step-by-Step Guide
Zeroing your rifle involves adjusting the sights to ensure your point of aim aligns with your point of impact at a specific range. This usually involves:
- Safe Handling: Always ensure your rifle is unloaded and handled safely before beginning the adjustment process.
- Choosing a Range: Start at a relatively close range (e.g., 25 yards) for initial zeroing.
- Adjusting for Windage: Make adjustments to the windage screw to align your point of impact horizontally.
- Adjusting for Elevation: Adjust the elevation screw to align your point of impact vertically.
- Testing and Refinement: After each adjustment, fire a few shots to check the results. Repeat the adjustment process as needed.
2. Identifying and Troubleshooting Common Issues
If your sights aren't performing optimally, consider these common issues and their solutions:
- Loose Screws: Ensure all screws are tightened securely.
- Sight Damage: Inspect the sights for any damage that could affect their functionality.
- Improper Installation: Make sure the sights are correctly installed on the receiver. Consult your owner's manual or a qualified gunsmith if you're uncertain.
Choosing the Right Rear Sight for Your Needs
Selecting the appropriate rear sight depends on your individual requirements and shooting style. Consider these factors:
- Intended Use: Will you primarily use iron sights or co-witness with optics?
- Shooting Environment: What conditions will you be shooting in (low light, bright light, etc.)?
- Budget: Prices vary among different models.
By understanding the different types of Rock River Arms rear sights and their proper adjustment, you can significantly improve your shooting accuracy and overall rifle performance. Remember always to practice safe gun handling and consult a qualified professional if you have any doubts or require assistance with your firearm.
