In the world of AR15 shooting, there's more than meets the eye. While red dot sights and rifle scopes often take center stage, there's an unsung hero that deserves attention - AR15 iron sights. These nifty tools offer a reliable backup for when your optics fail or provide a faster target acquisition method in close quarters.

The market is brimming with top-notch brands like Magpul Industries, TROY, FAB Defense, Leapers UTG, and Midwest Industries, each offering unique features and benefits. But don't worry, we're here to navigate through the maze of AR15 iron sights.

Whether you're a seasoned shooter or a newbie, this article will provide you with valuable insight into the world of AR15 iron sights. Stay tuned, and let's delve into the specifics of these indispensable tools.

Understanding Backup Iron Sights

Backup iron sights (BUIS) function as a reliable secondary targeting system for your firearm. More often than not, they serve as a fallback option in situations where the primary optic system fails, runs out of power, or sustains damage. Primarily, they're found on military-grade weapons but are equally beneficial for civilian uses too.

Two primary elements constitute iron sights, the 'front sight' and the 'rear sight'. The former is closer to the muzzle and generally sports a sharp point or a round dot. The latter, closer to the shooter, varies in design, including the 'open' and the 'aperture' types.

For instance, the AR15 A2 Non-Tritium Orange Standard Dot Front Sight presents itself as a simple and reliable front sight. It's bright orange dot contributes to a rapid target acquisition, while it's non-tritium ensures longevity.

Take into consideration, the UTG Super Slim RMR Mount 2 in 1 Combo Picatinny Black, a mount that showcases its versatility by catering to multiple height requirements. For example, it offers a 0.087 height mount position for an absolute co-witness with standard height AR iron sights and a low-profile 0.040 height mount for shotguns and rifles with traditional stocks.

Different Types of Backup Iron Sights

Transitioning from past discussion, let's dive into the world of Backup Iron Sights (BUIS). Distinct types exist, each made for specific requirements and scenarios. There are primarily three categories that make up the bulk of BUIS: Flip-Up, Fixed, and Offset Iron Sights.

Flip-Up Iron Sights

Flip-Up BUIS, often adjustable, offer the flexibility of being stowed away when not in use, hence the name. They're optimal when primary optics are in play, should you need secondary sighting option.

Fixed Iron Sights

Fixed Iron Sights remain in place continuously, eliminating any deployment time. This constant-readiness approach applies to users prioritizing unimpaired access to secondary sighting.

Offset Iron Sights

Finally, we encounter Offset Iron Sights, engineered to exist 45 degrees off the vertical plane. Ideal for tactical scenarios, quick transitions from primary optics to these aligned sights allow for seamless switching between distances or targets.

Why Do You Need Backup Iron Sights?

Backup Iron Sights (BUIS) represent a crucial component in enhancing tactical aptitude. They're not just an accessory, but a lifeline when electronic optics fail, adding a measure of robustness and reliability to engagements. Notably, BUIS come in three main categories – Flip-Up, Fixed, and Offset Iron Sights, each with distinct features to meet varying tactical requirements. It's not just about having a backup; it's about having a backup that works best for your operational needs.

Take, for instance, Flip-Up BUIS like the noted Troy Industries Micro HK Style or XS Sight Systems DXT Standard Dot sights. They're recognized for their rapid deployment and readiness, a quality inherent to their design. In a moment where time matters most, their quick flip-up feature provides immediate sight continuity, enabling accurate target acquisition. They can be the difference between an effective response or being a sitting duck.

Next, we've got Fixed Iron Sights. They're a constant cursor, always at the ready. With these BUIS, you're never left guessing; your sight line is always clear. Particularly helpful for situations that demand repeatably satisfactory, swift shots, Fixed BUIS like the AR15 A2 Non-Tritium Orange Standard Dot Front Sight, and the AR15 A2 CSAT Rear Sight, can be dependable allies.

Finally, we have Offset Iron Sights, those handy solutions for a seamless shift between primary optics and backup sights.

Co-Witness Definition and Use Case Scenarios

Co-witnessing means using both your iron sights and red dot sight simultaneously. It's an essential feature for sights, such as the AR-15 A2 CSAT Rear Aperture. In a full co-witness setup, iron sights align directly in the middle of the optic's field of view when looking through the optic in your normal shooting stance. In contrast, in a lower 1/3rd co-witness, the iron sights sit at the lower third of the optic.

Utilizing Co-witnessing helps in multiple scenarios. For instance, suppose the batteries on your optic run out, or it becomes damaged in a crucial situation. The iron sights step in and you can continue your aiming without a hitch. The AR-15 A2 Non-Tritium Orange Standard Dot Front Sight demonstrates this advantage perfectly.

Co-witnessing also aids in confirming the zero of your red dot. If your red dot aligns with your iron sights, you've got a confirmation your optic is on target. For instance, an AR-15 Tritium Flip Up Backup Iron Sights BUIS is compatible with this scenario.

Keep in mind that all iron sights may not co-witness with each optic. Each equipment might require a specific mount height depending on their design and configuration. It's important to ensure beforehand that your iron sight and your red dot sight are compatible for co-witnessing.

Co-witnessing serves as a solid backup plan, ensuring continuous aim, regardless of circumstances. It confirms your zero, provides immediate transition between optic and sights, and boosts overall reliability and accuracy.

Wrapping Up

So there you have it. Backup Iron Sights (BUIS) aren't just an accessory, they're a necessity for tactical readiness. Whether you opt for Flip-Up, Fixed, or Offset Iron Sights, remember it's all about enhancing reliability and accuracy in diverse conditions. As I've detailed, purchasing through authorized resellers ensures warranty coverage, giving you peace of mind. And let's not forget about Co-Witnessing. It's not just a fancy term, but a crucial aspect that ensures continuous aim and confirms zero when your primary optic might let you down. Compatibility between your iron sights and red dot sights is key for effective co-witnessing. Ultimately, choosing the right sights is vital to meet your operational needs. So take the time, do your research, and make the right choice for you. Trust me, you won't regret it.
