The KAC Ambidextrous Safety Selector Kit includes 3 different right hand
selector options to suit individual shooter preferences. There is the choice of
a full size right hand selector lever, a semi-scalloped right hand selector
that is low profile and less obtrusive, and a right hand indicator arrow that
provides a visual indication of the rifle's firing mode only. Installation is a
simple, drop-in procedure. Compatible with both SR-15/AR-15 and SR-25
platforms. Semi-auto only.
