The Magpul MBUS Front Sight delivers reliable backup sighting capability when primary optics fail or become damaged. This spring-loaded folding sight automatically deploys under pressure and locks securely in the upright position for immediate target acquisition.
What Makes This Different
Unlike fixed iron sights that create snag hazards, the MBUS folds completely flat when not in use while maintaining zero retention shot after shot. The sight post adjusts for elevation in half-MOA increments using standard AR-15 sight adjustment tools. Impact-resistant polymer construction withstands repeated deployment cycles and harsh environmental conditions that would damage metal alternatives.Key Features
