Abstract
A settable warhead burst range selector permits the user of a weapon to rdly change a chambered flechette ejecting projectile from a muzzle-burst mode to an extended-range mode. A slide containing a pyrotechnic delay is held in a neutral, muzzle burst mode, by a slide positioning locking plate. The pyrotechnic slide has flash ports along its length which are designed to cause flechette expulsion in either the muzzle-burst or the extended-range mode. The range mode is selected by twisting a knurled sleeve into a specific camming position. The sleeve is connected to a striker pin which projects into the weapon chamber area. The striker pin is capable of striking and dimpling the round in the chamber. A dimpled round will cause the slide positioning locking plate to detent the pyrotechnic slide so that the round will be in its extendedrange mode. An undimpled round will permit the pyrotechnic slide to move so that the round is in its muzzle-burst mode.
