Iron sights might seem old-school in the age of advanced optics, but for many AR-15 owners, they remain the preferred choice for various reasons. Reliability, simplicity, and affordability are key advantages. This guide dives deep into the world of AR-15 iron sights, helping you choose the best set for your needs and budget. We'll cover different types, factors to consider, and top recommendations.
Understanding AR-15 Iron Sight Types
There are several types of AR-15 iron sights, each with its own strengths and weaknesses:
A2 Style Sights
- Description: These are the classic, military-standard sights. They feature a post front sight and a notched rear sight, simple and robust.
- Pros: Reliable, inexpensive, readily available. A good starting point for many shooters.
- Cons: Can be less precise than other options, especially at longer ranges. The post front sight can be somewhat difficult to acquire in low-light conditions.
Low Profile Sights
- Description: Designed to sit lower to the rail, allowing for the use of magnified optics while still maintaining a backup sight.
- Pros: Co-witness capability with optics, low profile minimizes interference.
- Cons: May not offer the same sight radius as taller sights, potentially affecting accuracy at longer ranges.
Flip-Up Sights
- Description: These sights fold down when not in use, allowing for easy storage and less interference with optics.
- Pros: Convenient, protect the sights when not needed, allow for co-witnessing with optics.
- Cons: Can be more expensive than fixed sights, some models are less durable than others.
Adjustable Sights
- Description: Offer windage and elevation adjustments, allowing for precise zeroing at various distances.
- Pros: Versatility, accuracy improvements at different ranges.
- Cons: More complex, can be more expensive.
Key Factors to Consider When Choosing AR-15 Iron Sights
Selecting the right AR-15 iron sights involves careful consideration of several factors:
Sight Radius
- Definition: The distance between the front and rear sights. A longer sight radius generally improves accuracy.
- Impact: Longer sight radius allows for finer adjustments and better precision. Shorter sight radius can be more challenging, especially for less experienced shooters.
Material
- Options: Steel, aluminum, polymer. Steel is the most durable but heaviest. Aluminum offers a good balance of durability and weight. Polymer is lightweight and inexpensive but may be less durable.
- Considerations: Choose a material that matches your needs and budget. Consider the potential for wear and tear depending on your use case.
Height (Co-Witnessing)
- Definition: Refers to how the iron sights align with an optic, such as a red dot.
- Types: Absolute co-witness allows the iron sights to be seen clearly through the optic's window. Lower 1/3 co-witness places the iron sights slightly below the optic's window, which allows to keep the optic active and use the iron sight as back-up.
- Importance: Crucial if you plan to use your AR-15 with a magnified optic.
Durability
- Considerations: The sights should withstand recoil, impacts, and the elements. Steel is generally the most durable, followed by aluminum and then polymer.
- Impact: Durability is critical for reliable performance in demanding conditions.
Top AR-15 Iron Sight Recommendations
This is not an exhaustive list, and the "best" sights depend on individual needs and preferences. However, these are consistently highly-rated options:
(Note: Specific models and pricing change frequently. Always check current reviews and pricing before purchasing.)
| Brand | Model | Type | Material | Pros | Cons |
|---|---|---|---|---|---|
| Magpul | MBUS Pro | Flip-up | Steel | Durable, reliable, excellent reputation | Relatively expensive |
| Troy Industries | TRX Extreme Duty Sights | Fixed | Steel | Extremely durable, precise, reliable | High price point |
| Midwest Industries | Gen 2 Sights | Fixed/Flip-up | Aluminum | Excellent value, good accuracy | May not be as durable as steel sights |
| Aimpoint | Micro T2 (with mount) | Red Dot (Note: not iron sights but often paired with them) | Aluminum/Steel | Small and lightweight; reliable and excellent for CQB situations | Relatively expensive |
Conclusion: Choosing the Right AR-15 Iron Sights
Selecting the best AR-15 iron sights depends heavily on your intended use, budget, and preference. Consider the factors discussed above, research different models, and read reviews before making your purchase. Investing in a high-quality set of iron sights is a worthwhile investment for any responsible AR-15 owner. Remember to always practice safe gun handling and follow all local laws and regulations.
