Magpul's reputation for producing durable and innovative firearms accessories is well-earned. Their canted backup iron sights (BUIS) are a prime example, offering a practical and reliable sighting solution for users who want a robust secondary aiming system. This in-depth guide explores the benefits, features, and considerations surrounding canted Magpul BUIS.
Understanding the Need for Canted Backup Iron Sights
Before diving into the specifics of Magpul's offering, let's clarify why canted BUIS are beneficial. Traditional BUIS are typically aligned directly above the primary optic. However, a canted configuration provides several key advantages:
-
Faster Target Acquisition: With the sights offset, you can quickly acquire your target without needing to remove your primary optic from your line of sight. This is particularly advantageous in close-quarters combat (CQB) scenarios or during rapid transitions.
-
Improved Situational Awareness: Maintaining sight picture through the primary optic while simultaneously checking your surroundings is easier with canted BUIS. They allow for a more natural head position and minimize the need for extensive head movement.
-
Redundancy and Reliability: In the event of primary optic failure, having a reliable backup sight system is crucial. Canted BUIS offer a quick and simple means of maintaining accuracy and combat effectiveness.
-
Compatibility: Magpul's design ensures compatibility with various firearms and mounting systems. This versatility makes them a practical addition to a wide array of setups.
Magpul MBUS Pro: A Closer Look
Magpul's MBUS Pro line is a popular choice for canted BUIS. These sights are known for their:
-
Durable Construction: Made from reinforced polymer, they can withstand significant recoil and impact.
-
Low Profile Design: Their compact design keeps them out of the way when not in use, minimizing snags and reducing overall bulk.
-
Tool-less Adjustment: Windage and elevation adjustments are simple and can be performed quickly and easily, without the need for additional tools.
-
Ambidextrous Operation: Both the front and rear sights are designed for easy operation by both right-handed and left-handed shooters.
-
Co-witness Capabilities: Properly configured, these sights allow for co-witnessing with many red dot optics, allowing for a seamless transition between sights.
Choosing the Right Cant Angle
The cant angle of your BUIS affects how you use them. A common angle is 45 degrees, which offers a great balance between speed and accuracy. While less common, some shooters prefer a smaller or larger cant for specific shooting styles. Consider experimenting to determine what works best for you.
Installation and Zeroing
Magpul BUIS are designed for easy installation. However, precise zeroing is crucial for optimal accuracy. This process involves adjusting the sights to ensure accurate projectile placement at specific ranges. Many online resources provide detailed instructions for zeroing, which should be consulted before attempting this critical step.
Alternatives to Magpul Canted BUIS
While Magpul's MBUS Pro line are a popular choice, other manufacturers offer canted BUIS with various features and price points. Researching these alternatives can help you find the best option for your specific needs and budget. Always prioritize quality and reliability when choosing your backup iron sights.
Conclusion
Canted Magpul backup iron sights offer a significant advantage for any shooter prioritizing speed, reliability, and adaptability. The MBUS Pro line, in particular, represents a blend of quality, affordability, and user-friendliness. By understanding the benefits, features, and proper installation, you can enhance your aiming capabilities and ensure confidence in any shooting scenario.
