Ar-15 Imperial Buis Sight Set Black

The LMT Defense AR-15 Imperial BUIS Sight Set is a professional-grade backup iron sight system built for shooters who demand reliability across all conditions. This front and rear flip sight combo is engineered as a no-compromise alternative to optics-only setups, giving your 5.56 rifle the redundancy that matters when it counts.

The front sight features an internal clutch mechanism that allows controlled flex under stress while collapsing safely on impact. This design keeps the sight deployed with light pressure but folds down before it breaks—a feature born from real-world use rather than theoretical design. The rear sight uses a simple detent-locked up/down function paired with dual windage knobs and turret-style height adjustment for rapid sight-in. Dual peep apertures give you flexibility depending on your shooting distance and lighting conditions.

Whether you're running this set as backup to a primary optic or as your primary sighting system, the Imperial BUIS is built for the shooter who understands that iron sights aren't outdated—they're essential. With an effective range to 700 yards, these sights prove that modern backup iron sights can handle serious distance work.
