Abstract: Disclosed is an accessory mount configured for attachment to a rail interface system, such as the MIL-STD 1913 Picatinny rail. In particular, the accessory mount is a multi-position sliding mount that can be used to attach an accessory, such as a bipod or a tripod, to a handguard equipped with a compatible rail interface system. The accessory mount includes a spring-loaded push-button recoil lug that allows it to be quickly repositioned on a rail interface system. The accessory mount also includes an adjustment knob configured to facilitate attachment and removal without the need to slide the accessory mount on or off the end of the rail interface system. Additionally, the adjustment knob is configured to set sliding tension for the accessory mount and, if desired, to fix the accessory mount in position on the rail interface system.

Abstract: Disclosed is a firearm accessory with a clamping mechanism used to removably attach the firearm accessory to a rail system, such as a Picatinny rail. The clamping mechanism includes a pair of parallel engagement members and a reversibly extendable recoil lug, which is disposed within a guide groove in the firearm accessory. Additionally, the clamping mechanism includes a threaded fastener that is operatively connected to the recoil lug and is used to advance the recoil lug from, and retract the recoil lug into, the guide groove.
