The Noveske STS is an ambidextrous safety for your AR-15 that has a shorter 60 degree range between Safe and Fire; this is 30 degrees shorter than the standard safety. The Short Throw Selector (STS) is constructed with a stainless steel nitride selector drum and molded levers from MagPul Industries. The ambidextrous STS include 1 short lever and 1 long lever, which can be used on either side of the receiver. Installation of this selector requires a very small Jewelers flat blade screw driver (not included). This STS 60 degree safety is a drop in part, and will work with any Mil-Spec lower receiver.
This selector uses MagPul SSG Ambidextrous safety selector levers. For a custom setup, you can buy the SSG selectors and have dual short levers or dual long levers.
