A mounting for mounting an article onto a support comprising upper and lower mounting members. Seating surfaces provided between the members retain the members in assembled relationship with the members immovably registered together in a first plane. Three spaced mounting member registration projections provide, in the assembly, contact between the mounting members in three spaced and staggered positions on opposite sides of one of the mounting members, and registration to hold the members immovably together in a second plane. Spring-loaded locking is provided to hold the members together when assembled. Preferably the registration projections are provided on one member upon guide surfaces which are converging and inclined towards a respective seating surface. Guide surfaces on the other member are correspondingly converging and inclined. The convergence and inclination causes the projections to force the seating surfaces together to hold the members in the first plane while the projections themselves hold the members together in the second plane. One or other of the seating surfaces may have seating projections to engage the other seating surface. The invention is particularly applicable for use on weapons for withstanding sudden violent or vibrational forces and for quick release while permitting reassembly and while ensuring that settings such as calibration and boresighting settings are not altered.

1. A mounting for mounting an article upon a support comprising:first and second mounting members which are relatively movable into assembled relationship in which the second mounting member is held in a seating position by the first mounting member, each mounting member having a seating means, the seating means of the two mounting members lying in abutting relationship with the second mounting member immovably registered in a first plane relative to the first mounting member when the second mounting member is in the seating position, the mounting also comprising three spaced mounting member registration projections which are located to provide, in the seating position, contact between the mounting members in a three spaced position and staggered relationship from side to side of the second mounting member to register the second mounting member in a second plane relative to the first mounting member, the registration projections providing wiping action between the mounting members during their movement into assembled relationship; and means for locking the mounting members together with the second mounting member remaining in the seating position, wherein the locking means comprises a plurality of locking arms carried by one of the mounting members, each arm being spring-urged to move it into a position of locking engagement with the other mounting member when the second mounting member is in its seating position, and wherein there are two locking arms carried by the first mounting member and pivotable about pivot axes, respectively, to engage opposing sides of the second mounting member when the second mounting member is in its seating position.
