Description
The Magpul MBUS 3 Front Sight is a durable and low-profile back up sight system which mounts to any picatinny rail section. When not deployed the sight sits low on the rail staying out of the way of optics and can be quickly deployed by the push of a button. The MBUS 3 Front Sight sits at standard AR height when deployed, allowing you to co-witness with optics and features a tool-less elevation adjustment.
Features
- Tool-less elevation adjustment.
- Impact resistant polymer construction.
- Ambidextrous spring loaded mechanism allows sight deployment in any condition.
