An apparatus for locking a weapon support in either a zero position or any weapon-firing position relative to the turret of an armored vehicle. The apparatus includes a bore formed in the weapon support, a casing provided in the turret, and a bolt which engages the bore and protrudes through the casing into the interior of the armored vehicle. The bolt is spring-biased axially into engagement with the bore and the casing includes a gate. The bolt includes an index pin which engages the gate, the gate having first, second, and third defined positions for the index pin for latching and unlatching the weapon support.
