The opposing end of the legs may each have a notch. There may be a latch having a cam surface that is spring biased to protrude into the slot. The notches may receive the cam surface when the bipod is in the folded position, thereby releasably securing the opposing end of the legs within the slot.

Abstract: Shell holders for firearms have a body including a plurality of bores, a plurality of elastomeric elements, each associated with a different selected one of the bores, each elastomeric element having a protruding portion that protrudes a selected distance into the bore, a plurality of movable adjustment elements, each connected to the body and each operably engaged to a different selected one of the elastomeric elements, wherein the selected distance the protruding portion of the elastomeric element protrudes into the bore is adjustable based on an adjustment position of each adjustment element, and the selected distance is independently adjustable for each elastomeric element. The shell holder may be for a shotgun. The movable adjustment elements may include a plurality of jaws movable with respect to the body. There may be a gap defined between the body and each jaw. The elastomeric elements may be received within the gaps.

There may be a magazine having a body with an exterior profile sized to be closely and removably received in the magazine well, the body defining a central passage configured to receive a plurality of ammunition cartridges, the passage having an open upper end, a cartridge retention element attached to the body and movable between a first retention position, and a second released position.

Abstract: A butt pad apparatus is disclosed herein. In various aspects, the butt pad apparatus includes a plate and a recoil pad attachable to the plate such that a chamber is defined therebetween. The recoil pad with plate attached thereto may be adapted for attachment to a butt of a stock. In various aspects, the butt pad apparatus includes an insert removably receivable within the chamber, and the insert may be formed of an elastomeric material. This Abstract is presented to meet requirements of 37 C.F.R. §1.72(b) only. This Abstract is not intended to identify key elements of the apparatus and methods disclosed herein or to delineate the scope thereof.

Abstract: Magazines with detachable feed lip elements have a tubular body having a lower end and an upper end that defines an elongated passage that receives a spring and a detachable feed element positioned on top of the upper end of the passage that has feed lips that retain cartridges in the magazine and permit the cartridges to be extracted forwardly. The feed element may be a U-shaped device having a main upper panel that defines a feed lip aperture. The feed element may have side walls with fasteners that connect the feed element to the body. The feed element may have opposed sides, the aperture may be defined by the opposed sides, and a spring may be attached to one of the opposed sides to provide a biasing force toward the other opposed side such that a cartridge cannot be extracted from the aperture except in a forward direction.

Abstract: A firearm with movable cheek riser is a rifle stock having a stock body having a facility for receiving a rifle action and a rear extending portion, a stock butt portion telescopically connected to the rear extending portion, the butt portion being movable between a retracted position and an extended position, a cheek riser having a rear portion connected to the butt portion and a front portion connected to the stock body, and the cheek riser being movable between an elevated position and a lower position. The cheek riser may be pivotally connected to the butt portion. The cheek riser may include a downwardly-depending post received in a post bore defined in the stock body, wherein the post is curved such that a pivoting motion of the stock is facilitated. The invention may be a rifle including the rifle stock receiving a barreled rifle action.

Abstract: A golf car-mounted beverage dispenser designed to be used by golf course operators not only as a means for dispensing chilled beverages to its patrons, but also as a advertising medium. The beverage dispenser includes an inner half-cylindrical-shaped housing which is closed at one end and covered with a golf bag-simulating outer cover. Disposed longitudinally inside the housing is a cylindrical or square inner sleeve designed to receive a beverage tank filled with a desired beverage. The inner sleeve has a smaller diameter than the housing thereby creating an intermediate cavity between the housing and the inner sleeve for ice. Attached to the back of the housing is a mounting bracket for selectively attaching the housing to the support surface on a standard gas or electric powered golf car. Mounted on the sides of the housing is a second tank holding bracket used to hold a pressurized CO2 tank.
