Description
Magpul MBUS 3 Back-Up Front Sight – Flip-Up, Tool-Less Elevation, Ambidextrous Deployment, Black
Compact design. Reliable precision.
The Magpul MBUS 3 Back-Up Front Sight offers a rugged, low-profile solution for maintaining accurate aiming capability when optics are unavailable. Combining the proven performance of the MBUS line with upgrades inspired by the MBUS Pro, this flip-up sight delivers fast deployment, tool-less elevation adjustment, and durable construction for AR-platform rifles and carbines.
Built from impact-resistant polymer with corrosion-resistant hardware, the MBUS 3 is lightweight yet exceptionally strong. Its ambidextrous push-button mechanism allows easy deployment from either side, while the spring-tensioned design keeps the sight securely upright during use. Compatible with MIL-STD-1913 Picatinny rails, the MBUS 3 provides a dependable backup or primary sighting system for demanding environments.

-

Why It Stands Out:
Magpul’s MBUS 3 Front Sight blends the reliability and affordability of the MBUS series with refinements for even faster, easier use. Its tool-less elevation adjustment and ambidextrous deployment make it an excellent choice for shooters seeking a high-quality backup sight.
Perfect For:
AR-15 owners, tactical shooters, and enthusiasts needing a durable, flip-up front sight for backup or primary use.
