The AR-15 platform's versatility is partly due to its customizable nature. One of the most frequently upgraded components is the rear sight, often replaced with an A2 rear sight kit. This guide delves into the world of A2 rear sight kits, exploring their features, benefits, and considerations for AR-15 owners.
Understanding the A2 Rear Sight
The A2 rear sight is a classic and reliable component for the AR-15. Its design is simple yet effective, featuring an aperture (or "ghost ring") for aiming. This design offers a quick target acquisition, especially in close-quarters situations or during rapid target transitions. Its robust construction makes it durable enough to withstand harsh conditions and recoil. The A2 sight is also known for its adjustability, allowing for windage and elevation corrections.
Key Features of an A2 Rear Sight Kit:
- Aperture Design: Provides a clear sight picture, even in low-light conditions.
- Windage and Elevation Adjustments: Allows for precise zeroing at various ranges.
- Durability: Typically constructed from steel, offering superior strength and longevity compared to some polymer alternatives.
- Easy Installation: Usually straightforward to install, requiring minimal tools.
- Cost-Effective: A2 rear sight kits are generally affordable compared to more advanced sighting systems.
Choosing the Right A2 Rear Sight Kit
While the fundamental design remains consistent, several factors differentiate A2 rear sight kits:
Material:
- Steel: Offers the best durability and resilience. Steel A2 sights are preferred for their resistance to wear and tear.
- Aluminum: Lighter than steel, but potentially less durable.
Finish:
- Matte Black: The most common finish, providing a non-reflective surface.
- Other Finishes: Some kits might offer other finishes, like parkerizing or Cerakote, offering enhanced corrosion resistance.
Manufacturer:
Reputable manufacturers ensure quality and reliability. Researching different brands and reading reviews is crucial for making an informed decision. Look for brands with a proven track record of producing high-quality AR-15 components.
Benefits of Using an A2 Rear Sight Kit
- Reliability: A2 sights are known for their reliability and consistent performance.
- Simplicity: Their uncomplicated design minimizes the chances of malfunctions.
- Affordability: Compared to more sophisticated optic systems, A2 rear sights are budget-friendly.
- Durability: Built to withstand harsh conditions and recoil.
- Ease of Use: Simple to adjust and use, making them suitable for both beginners and experienced shooters.
Installation and Considerations
Installing an A2 rear sight is typically a straightforward process. Most kits include clear instructions. However, if you lack experience with AR-15 assembly, seeking assistance from a qualified gunsmith is recommended. Always prioritize safety when handling firearms.
A2 Rear Sight Kit vs. Other Sighting Systems
While A2 rear sights offer a robust and reliable solution, they are not the only option. Other sighting systems, such as red dot sights, holographic sights, and magnified optics, offer different advantages and disadvantages. The best choice depends on the intended use and individual preferences.
Conclusion
The A2 rear sight kit remains a popular choice for AR-15 owners due to its reliability, affordability, and ease of use. Understanding the features, benefits, and considerations discussed above will help you choose the right kit for your specific needs. Remember to always prioritize safety and handle firearms responsibly.
