Tachyon Arrow
From Warhammer 40k - Lexicanum
A Tachyon Arrow is a wrist-mounted energy weapon used by Necrons. When activated, it transmutes a sliver of inert metal into an unstoppable thunderbolt capable of piercing a mountain.[1]
The single-shot variants are tremendously powerful, capable of firing a projectile at the speed of light, which can instantly destroy an Imperial Titan.[2]
