Wikipedia Made to correct the odd and often makeshift mounting solutions while using the MP5 with modern white light and laser setups, we came up with the Normalized Activation Switch (NAS). This mount, created for use with the full compact Modbutton Lite, allows for ambi use while creating minimal snag points when using the unconventional, albeit novel HK roller locked style charging handle. Built on even smaller size constrains the Normalized Activation Switch, Kurtz (NAS-K) is a solution for white light and laser use on the MP5K/PDW. Because of its mounting on the front sight’s tri-tower it can be used with a myriad of other HK models and handguard types from the modern MLOK type to the classic “room broom” type. The NAS-K can also be used in conjunction with the full size NAS to allow for two independent switches to be secured end to end, much like the Insight dual switches.
