Magpul's MBUS (Magpul Back-Up Sights) have become a staple for many firearm enthusiasts, offering a robust and reliable backup sighting system. But what about the canted version? This seemingly small modification significantly alters the sighting experience and opens up tactical advantages often overlooked. Let's dive deep into the benefits and considerations of using canted Magpul backup iron sights.
Why Choose Canted BUIS?
The primary advantage of canted BUIS lies in their ability to offer a rapid transition between primary optic sighting and backup iron sights. Instead of needing to dramatically shift your head position or posture when transitioning from a scope or red dot to irons, a canted setup allows for a more natural, quicker sight picture. This is particularly crucial in dynamic situations where speed and accuracy are paramount.
Faster Target Acquisition
The canted design allows for a more streamlined transition. You're not fighting awkward head positioning or trying to force a new cheek weld. This translates directly to faster target acquisition, a crucial element in self-defense and competitive shooting.
Reduced Eye Strain
Maintaining a consistent cheek weld with different sighting systems can be tiring, especially during prolonged use. Canted BUIS mitigate this issue, reducing the need for major adjustments and reducing eye strain.
Understanding the Mechanics
Canted sights are typically mounted at a 45-degree angle relative to the main optic. This angle allows the shooter to use the iron sights without significantly altering their shooting posture or head position. The specific cant angle may vary slightly depending on the manufacturer and model, so always check your specific setup's instructions.
Compatibility and Installation
Magpul MBUS sights are renowned for their compatibility with a wide range of platforms. The canted version maintains this versatility, fitting easily onto most Picatinny or Weaver rails. Installation is generally straightforward, though careful attention to proper alignment is essential for accurate sighting.
Tactical Advantages
The advantages extend beyond pure speed. The canted configuration often provides a more natural and intuitive point of aim, particularly when engaging targets at close quarters or in less-than-ideal shooting positions. The slight offset can enhance situational awareness, allowing a quicker assessment of the surrounding environment while keeping the sights ready.
Close-Quarters Combat (CQB)
In CQB scenarios, the speed advantage of canted BUIS is invaluable. The ability to quickly acquire a sight picture without readjusting your grip or posture can be the difference between success and failure.
Drawbacks and Considerations
While canted BUIS offer significant benefits, some drawbacks warrant consideration.
Zeroing and Adjustment
Zeroing canted sights might require slightly more effort compared to standard BUIS due to the angled nature of the setup. Precise adjustment is vital to ensure accurate shots.
Potential for Confusion
Some shooters may initially find the canted configuration slightly disorienting, requiring a period of adjustment and practice to become fully proficient.
Not for Everyone
The canted setup isn't universally preferred. Some shooters find it uncomfortable or simply prefer the traditional alignment. The ideal choice depends on individual shooting style and preferences.
Conclusion: The Right Tool for the Job
Canted Magpul backup iron sights represent a significant evolution in backup sighting systems. While not ideal for every shooter or scenario, their speed advantages, reduced eye strain, and enhanced situational awareness make them a compelling option for many. Careful consideration of individual needs, alongside sufficient practice and familiarization, is key to leveraging their full potential. Ultimately, whether or not canted BUIS are the "right tool" depends entirely on your individual shooting requirements and preferences.
