Elevate Your Aim: The Magpul MBUS Pro LR Adjustable Rear Sight – Precision for the Discerning Shooter

For firearms enthusiasts, competitive shooters, and tactical professionals who demand unwavering reliability and adaptable precision from their AR-platform rifles, the Magpul MBUS Pro LR Adjustable Rear Sight in Black stands as an indispensable upgrade. This isn't just a backup sight; it's a meticulously engineered tool designed to excel when primary optics fail, or when variable-distance engagements call for rapid, no-tool elevation adjustments. Crafted for the rigorous demands of modern shooting, this Magpul innovation answers the call for a durable, low-profile, and highly accurate sighting solution that complements any AR-15 setup.

Are you an AR-15 owner looking to enhance your rifle's versatility? Do you need a robust, low-profile iron sight that can quickly adjust for targets at different ranges? The Magpul MBUS Pro LR (MAG527-BLK) directly addresses these critical needs, providing a distinct advantage in dynamic shooting environments, from the competition range to the field.

Unlocking Precision: Key Features and Benefits for Peak Performance

The Magpul MBUS Pro LR is a testament to Magpul's commitment to innovation and quality. Every aspect of its design is optimized for performance, durability, and user-friendly operation.

Dynamic Elevation Adjustment for Variable Distances

One of the standout features that sets the MBUS Pro LR apart is its integrated elevation adjustment wheel. This precision-engineered mechanism allows shooters to rapidly transition between target distances, making it ideal for scenarios where engagements occur across varied ranges. The elevation wheel is specifically calibrated for 200-600 meter distances, with precise 50-meter increment adjustments.

• How it enhances shooting: This capability means you can quickly dial in your elevation without fumbling for tools, ensuring your point of aim aligns with your bullet's trajectory, whether you're engaging a close-range target or stretching your rifle's capabilities out to several hundred meters. For competitive shooters, this translates to faster stage times and greater accuracy on multi-target courses. For hunters or tactical users, it offers critical adaptability when target distances are uncertain or rapidly changing.
• Practical application: Imagine a scenario where you've sighted in your rifle at 100 meters, but an unexpected target appears at 300 meters. With the MBUS Pro LR, a quick rotation of the elevation wheel is all it takes to adjust your point of impact, minimizing holdover and maximizing your chance of a precise hit.

Unrivaled Durability: All-Steel Construction with Melonite Finish

When your life or mission depends on your equipment, compromise is not an option. The Magpul MBUS Pro LR is constructed entirely from steel, ensuring maximum strength and resistance to impact. Unlike sights made from lesser materials, this steel construction maintains zero under harsh conditions, absorbing recoil and resisting flex.

• The Melonite advantage: The steel components are meticulously case-hardened and then finished with Melonite. Melonite is a salt bath nitriding process that dramatically enhances surface hardness, wear resistance, and corrosion resistance. This treatment provides a virtually impenetrable barrier against rust, abrasion, and chemical exposure, ensuring your sights maintain their pristine condition and functionality even after prolonged exposure to the elements or extreme use.
• Why it matters: This superior finish means your sights will withstand rain, mud, dust, and even saltwater environments without degradation, making them an ideal choice for serious users who operate in demanding climates or tactical situations. The longevity provided by the Melonite finish also translates to a lower total cost of ownership over the lifetime of your firearm.

Streamlined, Low-Profile Design for Unobstructed Operation

The original MBUS Pro set a new standard for low-profile design, and the MBUS Pro LR capitalizes on this success. When stowed, this rear sight boasts an incredibly low height of just 0.49 inches.

• Benefits of a low profile:
  • Unimpeded Sight Picture: This minimal footprint ensures that the sight does not obstruct your view when using primary optics like red dot sights or scopes. It allows for a clearer, less cluttered sight picture, crucial for rapid target acquisition.
  • Snag-Free Operation: A sleek, low-profile design reduces the chance of snagging on gear, clothing, or vegetation, which is vital in fast-paced tactical scenarios or during movement.
  • Seamless Co-witnessing: Its compact nature allows for effortless co-witnessing with many popular red dot optics, providing a reliable backup without interfering with your primary sighting system.
• Positive Detents: When deployed, the MBUS Pro LR locks securely into a standard AR sight height, providing a consistent and repeatable sight picture. The positive detents ensure the sight stays deployed until you choose to fold it down, offering unwavering stability during firing sequences.

Optimized Aperture System for Versatile Engagement

The MBUS Pro LR features two distinct apertures to suit various shooting scenarios:

• Small Aperture (0.07 inches): Ideal for precision shooting at longer ranges where a clear, defined sight picture is paramount. This aperture helps to sharpen the focus on the front sight post and target.
• Large Aperture (0.19 inches): Designed for rapid target acquisition in close-quarters combat (CQC) or high-stress situations where speed is more critical than pinpoint accuracy. It allows for more light and a broader field of view, making it easier to acquire targets quickly.
• Effortless Transition: Switching between the apertures is quick and intuitive, allowing shooters to adapt their sight picture to the immediate demands of the situation.

Tool-Free Windage Adjustments for On-the-Fly Corrections

Beyond elevation, the MBUS Pro LR also offers precise, tool-free windage adjustments at 0.50 MOA per click. This feature allows shooters to compensate for environmental factors like crosswinds or refine their zero without needing external tools. The audible and tactile clicks ensure precise and repeatable adjustments.

Proudly Made in the USA

As with all Magpul products, the MBUS Pro LR is proudly manufactured in the USA. This commitment to domestic manufacturing ensures superior quality control, adherence to strict standards, and a product you can trust to perform when it matters most.

Who is the Magpul MBUS Pro LR For? Real-World Applications

The versatility and robust construction of the Magpul MBUS Pro LR make it an excellent choice for a wide array of users and applications:

• AR-15 Owners & Builders: Essential for any AR-platform rifle, serving as a primary sight or a rock-solid backup to optics. Perfect for new builds or upgrading existing rifles.
• Competitive Shooters (e.g., 3-Gun): The rapid elevation adjustment is a game-changer for stages with varying target distances, allowing for quick transitions and improved scores.
• Tactical and Law Enforcement Professionals: Reliability, durability, and quick deployment are paramount in critical situations. The MBUS Pro LR provides a trusted secondary sighting system.
• Hunters: Ideal as a backup sight when hunting with optics, ensuring you can still make an ethical shot if your scope fogs up, breaks, or its battery dies.
• Home Defense & Self-Defense Users: A reliable iron sight is crucial for a defensive firearm, providing a robust solution that doesn't rely on batteries.
• Training & Range Enthusiasts: Helps shooters understand ballistic principles and sight adjustments without relying solely on electronic optics.

Optimizing Your AR-15: Installation and Zeroing Insights

Installing the Magpul MBUS Pro LR Adjustable Rear Sight is straightforward, designed for compatibility with any MIL-STD 1913 Picatinny rail or STANAG 4694 rail, which are standard on most AR-platform rifles. Its intuitive design ensures a snug, secure fit without complex mounting procedures. Once mounted, the next crucial step is zeroing your sight.

• Simplified Zeroing: The precise windage (0.50 MOA clicks) and elevation (50M increments) adjustments make the zeroing process efficient. Begin by sighting in your rifle at a standard distance (e.g., 50 or 100 yards) using the small aperture for maximum precision. Once a reliable zero is established at your primary distance, you can then utilize the elevation adjustment wheel for rapid compensation at other known distances, making target engagement incredibly efficient. The "no-tool" nature of the adjustments allows for fine-tuning on the fly at the range.

Common Questions About the Magpul MBUS Pro LR

Here are answers to frequently asked questions about this premium Magpul rear sight:

• Is the Magpul MBUS Pro LR compatible with all AR-15s? Yes, it is designed to mount seamlessly onto any standard MIL-STD 1913 Picatinny rail or STANAG 4694 rail, which is the universal mounting platform for AR-15s and many other modern sporting rifles.
• How does the Melonite finish compare to other firearm coatings? Melonite is a superior treatment compared to traditional bluing or even some parkerizing finishes. It creates a hardened surface that is incredibly resistant to wear, corrosion, and chemicals, offering enhanced durability and longevity for your sight.
• Can I use the MBUS Pro LR with a red dot sight or scope? Absolutely. Its ultra-low profile when stowed (0.49 inches) means it will not obstruct your primary optic's view. It's an excellent choice for co-witnessing with many red dots, allowing you to use your iron sights through your red dot optic as a backup.
• What's the difference between the standard MBUS Pro and the MBUS Pro LR? The primary difference is the "LR" or "Long Range" designation. The MBUS Pro LR includes an integrated elevation adjustment wheel (for 200-600M distances with 50M increments), while the standard MBUS Pro rear sight primarily offers windage adjustments. The LR model is ideal for shooters needing quick elevation changes for variable distances.
• Why choose steel sights over polymer ones? While polymer sights offer advantages in weight and cost, steel sights like the MBUS Pro LR provide superior durability, impact resistance, and maintain zero more consistently under extreme conditions or direct impacts. Steel is less susceptible to thermal expansion or deformation under stress, ensuring long-term reliability.
• What kind of maintenance does it require? Due to its Melonite finish, the MBUS Pro LR is incredibly low maintenance. A simple wipe-down with a clean cloth after use and occasional light oiling (though often unnecessary) will keep it in prime condition. Its robust construction minimizes the need for intricate upkeep.
• Is it heavy for a backup sight? At just 2 ounces, the Magpul MBUS Pro LR is remarkably lightweight for an all-steel sight, adding minimal bulk to your rifle while offering maximum strength.
