Magpul MBUS 3 Front Sight – Flat Dark Earth
The Magpul MBUS 3 Front Sight is the next evolution in the MBUS (Magpul Back-Up Sight) series, combining the best features of the original MBUS and MBUS Pro Sights into a compact, lightweight, and highly durable backup sight system.
Significantly reduced in size, the MBUS 3 Front Sight measures only 0.47 inches high when folded, 1.38 inches at its widest point, and weighs just 25 grams with hardware. Designed with a sleek profile inspired by the MBUS Pro, this front sight is constructed from Magpul’s impact-resistant polymer, offering both lightweight performance and rugged durability. Like its predecessors, the MBUS 3 features spring-loaded deployment, allowing for quick activation via an ambidextrous push-button mechanism.
When deployed, the MBUS 3 Front Sight sits at standard AR-height and includes a tool-less elevation adjustment system with a dual-width enhanced front post similar to the MBUS Pro. This ensures precise adjustments and quick adaptability in dynamic shooting situations.
Note: This sight is not compatible with railed gas blocks due to potential heat exposure. It must be mounted to a railed forend on the same plane as the receiver rail and is not compatible with MOE Hand Guards.
