US12638268 - Extendable blade firearm attachment device

An extendable blade firearm attachment device includes a handguard configured to mount to a barrel of a firearm. An elongated monopod is coupled to the handguard. The monopod has a main body and a connection to the handguard such that the monopod is movable between an extended position and a retracted position. The monopod extends away from the handguard from a proximal end to a distal end when in the extended position. A monopod fastener removably couples the monopod to the handguard. A knife blade is pivotably coupled to the monopod to be pivotable between a closed position and an open position. A spine of the knife blade is exposed relative to the monopod when the knife blade is in the closed position.

The patent describes an extendable blade attachment for firearms that includes a handguard and a movable monopod, which can be extended or retracted. A knife blade is pivotably attached to the monopod, allowing it to transition between closed and open positions while remaining securely coupled to the firearm.

Claim 1

1 . A firearm attachment comprising: a handguard configured to mount to a barrel of a firearm; a monopod coupled to a bottom side of said handguard, said monopod being elongated between a proximal end of the monopod relative to said handguard and a distal end of the monopod relative to said handguard, said monopod having a main body and a connection to said handguard such that said monopod is movable between an extended position and a retracted position, said monopod extending away from said handguard from said proximal end to said distal end when in said extended position; a monopod fastener removably coupling said monopod to said handguard; and a knife blade pivotably coupled to said monopod, said knife blade being pivotable between a closed position and an open position, a spine of said knife blade being exposed relative to said monopod when said knife blade is in said closed position. a handguard configured to mount to a barrel of a firearm; a monopod coupled to a bottom side of said handguard, said monopod being elongated between a proximal end of the monopod relative to said handguard and a distal end of the monopod relative to said handguard, said monopod having a main body and a connection to said handguard such that said monopod is movable between an extended position and a retracted position, said monopod extending away from said handguard from said proximal end to said distal end when in said extended position; a monopod fastener removably coupling said monopod to said handguard; and a knife blade pivotably coupled to said monopod, said knife blade being pivotable between a closed position and an open position, a spine of said knife blade being exposed relative to said monopod when said knife blade is in said closed position.
