US12742619 - Two-stage multiuse gun clearing and test trap with replaceable decelerant

A reusable gun clearing and test trap has two chambers, a bullet capture chamber and an attached bullet inlet chamber to stop fired bullets, the capture chamber having at least one user-serviceable door for interior access to receive a bullet decelerant. An elastomeric mass such as blocks of compressed crumb rubber or vulcanized virgin rubber retardant is removably insertable into the inlet chamber for slowing the fired bullets. A slurry, such as a mixture of sand and oil such as is removably loadable into the capture chamber through a trap door and serves as the decelerant for the fired bullets. The capture chamber and the inlet chamber are made in a shape and of encasing materials that are sufficient to contain explosive discharges and ricochets associated with fired bullets. A labyrinth baffle is for dispersing discharge gases.

US12687360 - Chamber obstruction device for firearm

A device includes a locking mechanism that transitions between a locked state and an unlocked state. The locking mechanism has a first depressible member that actuates in a first direction and second depressible members that actuate in a second direction different than the first direction. Fastening mechanisms that secure the second depressible members to the device. A cover transitions between a first position in which the fastening mechanisms are obstructed and a second position in which the fastening mechanisms are unobstructed. The cover transitions from the first position to the second position in the unlocked state of the locking mechanism. A slide engages with the cover and permits transitioning of the cover from the first position to the second position.
