Finding the right AR-15 scope mount is crucial for accurate shooting. But what if you want to retain the use of your iron sights? This guide dives deep into choosing an AR-15 scope mount that allows for co-witnessing or lower 1/3 co-witnessing of your iron sights, ensuring you have a backup sighting system. We'll cover different types of mounts, their pros and cons, and what to consider when making your purchase.

Understanding Co-Witnessing and AR-15 Iron Sights

Before we delve into specific mounts, let's clarify the importance of co-witnessing your iron sights with your scope. Co-witnessing means that you can see both your iron sights and your scope's reticle simultaneously. This provides redundancy – if your scope malfunctions or your battery dies (in the case of illuminated reticles), you still have a reliable aiming solution.

There are two primary types of co-witness:

• Absolute Co-witness: Your iron sights appear directly in line with your scope's reticle. This gives you a clear, unobstructed view of both.

• Lower 1/3 Co-witness: Your iron sights sit slightly below the scope's reticle. This setup is generally preferred as it provides a wider field of view with the scope, while still allowing you to use your iron sights as a backup. The iron sights will appear to be 1/3 of the way down from the center of your scope's reticle.

Most AR-15 owners prefer a lower 1/3 co-witness setup for the best balance between scope and iron sight usability.

Types of AR-15 Scope Mounts that Allow for Iron Sight Co-Witnessing

Several mount types accommodate iron sights. Here’s a breakdown:

1. Standard AR-15 Scope Mounts with Different Heights

Standard mounts come in various heights, directly affecting the level of co-witnessing. The height is usually measured in terms of how high the scope sits above the receiver. A lower mount will result in a lower 1/3 co-witness (or even no co-witness), while a higher mount might result in an absolute co-witness or even obstruct the iron sights entirely. Always check the manufacturer's specifications for height and intended co-witnessing configuration.

Pros: Widely available, generally affordable.

Cons: Requires careful selection to achieve the desired co-witness. Incorrect height selection can render your iron sights unusable.

2. AR-15 Scope Mounts with Integrated Sighting Systems

Some mounts incorporate features to improve sight alignment. These might include built-in backup iron sights or other features aiding in sighting.

Pros: Integrated design can enhance usability and co-witnessing.

Cons: Usually more expensive than standard mounts.

3. Offset AR-15 Scope Mounts

These mounts position the scope off to one side of the receiver, allowing for clear use of the iron sights without obstructing the scope's view.

Pros: Keeps iron sights unobstructed, even with a high scope mount.

Cons: Can compromise handling and require significant practice to become proficient. The offset can affect shooting consistency for some users.

Factors to Consider When Choosing an AR-15 Scope Mount with Iron Sight Capability

• Height: This is the single most important factor determining your co-witnessing setup. Carefully check the manufacturer's specifications to ensure it’s compatible with your scope and desired co-witnessing style.
• Material: Aluminum is the most common material, offering a good balance of strength and weight. Steel is heavier but more durable.
• Durability: The mount must withstand recoil and maintain zero. Look for mounts made from high-quality materials and featuring robust construction.
• Scope Ring Diameter: Make sure the scope rings are compatible with the diameter of your scope's objective lens and body.
• Weight: A lighter mount is generally preferable, but don't compromise durability for weight savings.
• Price: Mounts range from budget-friendly options to high-end, feature-rich models. Set a budget before you start shopping.

Conclusion: Choosing the Right AR-15 Scope Mount with Iron Sight Capability

Choosing the right AR-15 scope mount that allows for iron sight co-witnessing is vital for maintaining a backup sighting system. Carefully consider factors such as mount height, material, durability, and your desired co-witnessing style. Prioritize quality to ensure your mount can withstand the rigors of shooting and maintain zero. Remember, the best mount is the one that meets your specific needs and budget while ensuring reliable and accurate shooting. Remember to always consult your firearm's manual and seek advice from experienced shooters.
