Flip up sight kit for Picatinny rail - Hera Arms

Our HBUS series of emergency sights are among the most compact solutions on the market. With a height of only approximately 11 mm and a length of approximately 40 mm, they set the technical minimum of what is feasible – while maintaining the standard height of common AR-15 sights.

This is made possible by an innovative, counter-rotating mounting position: The HBUS has the rotation axis in front of the mounting screw, ensuring an extremely compact design when folded.

HERA emergency sights are made of impact-modified plastic, while the spindles, adjustment mechanism, and screws are made of steel and surface-finished using the QPQ process. The HBUS combines uncompromising, sophisticated design with maximum compactness without compromising full compatibility with AR-15 systems and standardized mounts.
