The RAILSCALES Karve® is an innovative KeyMod and M-LOK hand stop; thanks to the COG™ Multi-Mount system and the included hardware, you can easily attach the lightweight hand stop to either rail system. Being reversible, it allows for either a “push” or “pull” style grip. Focusing as much attention on the contoured front surface as well as the dimpled rear, the Karve® handstop allows for numerous shooting positions and styles in a compact, ultralight, durable package.
