Abstract
Disclosed is a reversible safety selector switch for an AR15-type firearm including a control shaft and a control lever. The control shaft is pivotably mountable about an axis in a lower receiver and has a cam portion with first and second cam surfaces and a detent portion having a surface and first and second detent grooves with detent sockets at each end of each groove. The first detent groove extends circumferentially approximately 90 degrees along the surface and the second detent groove extending circumferentially less than 90 degrees along the surface. A control lever is connectable to an end of the control shaft and configured for manipulation outside the receiver by a user to axially rotate the control shaft. When the selector is installed in the receiver, a detent pin in the receiver engages one of the detent grooves and prevents axial rotation beyond a detent socket, the first cam surface and first detent groove are positioned to allow axial rotation of the shaft between “safe” and “fire” positions in approximately 90 degrees of rotation and the second detent groove being positioned to allow axial rotation of the shaft between “safe” and “fire” positions in less than 90 d…
