The Byrna BM68931 ProFiber Topcover Kit is a purpose-built upgrade for Byrna SD and LE launchers, replacing the factory top cover with a precision slide featuring ultra-bright fiber optic sights. Designed to enhance sight visibility and alignment, this kit delivers a crisp, easy-to-acquire sight picture across a wide range of lighting conditions while maintaining full compatibility with the SD/LE platform.

This drop-in topcover assembly is ideal for owners who want faster target acquisition and more confidence behind their less-lethal launcher without altering its core ergonomics. The fixed fiber optic sight system supports training, home protection readiness, and general range use, giving shooters a clear visual reference that promotes consistent accuracy. Built as a genuine Byrna accessory, it reflects the brand’s focus on practical innovation and dependable performance.
