Choosing the right sights for your firearm is crucial for accuracy and speed. Magpul's MBUS (Magpul Back-Up Sight) line is a popular choice among many shooters, offering robust and reliable backup sights. But with the introduction of the MBUS Pro, the choice has become more complex. This in-depth comparison will help you decide which sight – MBUS or MBUS Pro – is right for you. We'll explore the key differences, advantages, and disadvantages of each to guide you towards an informed decision.
Key Differences Between MBUS and MBUS Pro
The main differences between the MBUS and MBUS Pro lie in their materials, features, and overall design. While both serve as reliable backup sights, the Pro model offers several upgrades.
Material and Construction
-
MBUS: Constructed primarily from polymer, the MBUS is lightweight and durable, though some users have reported issues with polymer wear under extreme conditions.
-
MBUS Pro: Utilizes a reinforced polymer body with steel components for critical areas like the sight posts. This makes the MBUS Pro significantly more durable and resilient to impacts and wear compared to the original MBUS.
Sight Adjustment
-
MBUS: Features a simple, tool-less windage and elevation adjustment system, but this system lacks the precision of the Pro model.
-
MBUS Pro: Employs a more precise, tool-less adjustment system that provides finer control over windage and elevation adjustments. This precision is crucial for accurate zeroing and adjustments in the field.
Sight Post Design
-
MBUS: Uses a simpler, less refined sight post design.
-
MBUS Pro: Features a significantly improved sight post design. The posts are thicker and more robust, improving visibility and reducing glare in various lighting conditions. The front sight post features a larger, more visible post that makes target acquisition quicker and more intuitive.
Overall Design
-
MBUS: Offers a more compact and minimalist design that prioritizes lightweight construction.
-
MBUS Pro: Slightly bulkier and heavier than the MBUS due to the inclusion of steel components, offering a more robust build that prioritizes durability and precision.
