Abstract: A portable implement releasable holder is provided which has a base for securing to a rigid support therefore, and a first implement support member attached to the base and projecting upwardly therefrom. That first member has an enlarged uppermost portion which is sufficient in size to receive the stock of a sporting firearm, along with a downwardly disposed recess capable of receiving a portion of the handle of a fishing rod. A second implement support member is attached to the base and projects upwardly therefrom to a distance less than the distance of the first member. The second support member has an upwardly curved configuration such that a portion of the second member can receive and retain the butt portion of the stock of the sporting firearm. A clamping means is provided to secure the base to the support therefore.
