US12504255 - Firearm accessory coupling system

The patent describes an interchangeable firearm accessory coupling system that features an elongated connecting member with a recess for receiving a firearm bore accessory component, which is engaged or disengaged via a translatable sleeve. This design includes a resilient component that biases the sleeve towards the engaged position, ensuring secure attachment and alignment of the accessory.

Claim 1

1 . A firearm accessory coupling system, comprising: an elongated connecting member having a rearward end and a forward end, including: a middle body component; and an accessory-end component, wherein said accessory-end component includes a recess cut therethrough; a sleeve in translational engagement with said elongated connecting member’s accessory-end component; a resilient component within an interior portion of said elongated connecting member, capable of recovering its size and shape after deformation caused by compressive stress, said resilient component biasing said sleeve in a direction towards said elongated connecting member forward end; a loading element comprising a locking member at a rear end having a bulbous end and a shaft that extends the bulbous end from an intermediate flange, configured to be received by said recess within said accessory-end component recess at said elongated connecting member forward end, and said intermediate flange extending radially outwards; a receiving coupler attachable to said rearward end of said elongated connecting member; and a firearm bore accessory component removably attachable to said loading element; an elongated connecting member having a rearward end and a forward end, including: a middle body component; and an accessory-end component, wherein said accessory-end component includes a recess cut therethrough; a sleeve in translational engagement with said elongated connecting member’s accessory-end component; a resilient component within an interior portion of said elongated connecting member, capable of recovering its size and shape after deformation caused by compressive stress, said resilient component biasing said sleeve in a direction towards said elongated connecting member forward end; a loading element comprising a locking member at a rear end having a bulbous end and a shaft that extends the bulbous end from an intermediate flange, configured to be received by said recess within said accessory-end component recess at said elongated connecting member forward end, and said intermediate flange extending radially outwards; a receiving coupler attachable to said rearward end of said elongated connecting member; and a firearm bore accessory component removably attachable to said loading element; wherein said sleeve is translatable between an engaged position wherein said sleeve encloses said recess, to a disengaged position wherein said sleeve moves toward said middle body component of the elongated connecting member, thereby exposing said recess; and wherein said intermediate flange contacts and engages said accessory-end component at a forward end opening of said elongated connecting member forward end, ensuring coaxial alignment of said firearm bore accessory component with said elongated connecting member.
