Abstract: An accessory mounting device to pivotably mount an accessory to a weapon such as a firearm provides recoil dampening and generally may also include an accessory mount, a weapon attachment base, an arbor, and a detent mechanism. Advantageously, to flip or rotate the accessory mount through about 90 degrees between a first position above the base and a second position along a side of the base requires only grasping the accessory mount and rotating it from either of the positions through 90 degrees to the other position. No separate manual action to disengage any type of locking device is required, nor is any longitudinal or lateral translation of the mount involved. The function of providing stabilized, consistent location in each of the two positions, resistance to movement from each position, and manual movement of the mount that overcomes the resistance and rotates between the positions is provided by the detent mechanism.

Abstract: A quick release pin is used in a firearm to secure a barrel assembly to a frame and a recoil assembly within a slide. The cylindrical body of the pin functions similarly to traditional takedown pins and pivot pins used with firearms while the lever arm has unique features that are an improvement over traditional takedown pins. The arm has a locking lip at its proximate end, a detent at its distal end, and a cut-out center section which is thinner than the distal end and proximal end. The cut-out center section creates a space between the arm and the firearm's side when the arm is in its locked configuration which provides side edges for a user to grasp the edges of the arm between a finger and thumb while the thicker distal end of the arm is in flush contact with the side of the firearm.
