Abstract
Abstract A gunsight mount composed of two support members, an upper sight support member and a lower attaching post member, is disclosed. One of the members has a recess, the other a projection fitting into the recess. A spring biased cam operated jaw is slidably mounted in the recess member transverse the recess. Operating the cam forces the jaw into the recess against the projection securing the sight support to the attaching post. Releasing the cam frees the jaw which is biased away from the projection and out of the recess allowing the sight mount to be removed or reinserted without interference from the jaw.
