A fluid lubricated projectile trap includes a substantially cylindrical chamber defined by a forward concave wall and a rearward concave wall. A bullet funnel extending forwardly therefrom. The funnel having a lower panel connecting to the forward concave wall in conjunction with an end plate defines a pressurized fluid containment with discharge outlets directed to the rearward concave wall. All plumbing may be secured below the ramp and forward of the chamber.

A bullet trap is disclosed which comprises a vibration dampening gasket disposed between the impact plates and support frame.

A gun-clearing box, which comprises: a box-body having a gun-clearing space inside, a cover opening and an assembly opening connecting the gun-clearing space to the outside; a cover-body; a gun-placing barrel having an placing entrance, a shot exit, and a barrel wall connected between, wherein the diameter of the placing entrance is larger than which of the shot exit; wherein the gun-placing barrel is fixed in the assembly opening, and the placing entrance is faced toward the outside of the box-body, and the shot exit is inclined to face toward the gun-clearing space; and a sliding-sleeve abutting assembly set in the gun-placing barrel, wherein the sliding-sleeve abutting assembly has two adjacent abutting surfaces with a gap between; wherein the gap is inclined and reduced along the direction from the placing entrance to the shot exit; thereby improving the convenience and safety of the use.

A bullet resistant wall system including ballistic paver blocks constructed, configured, and arranged to form a wall having at least two adjacent individual layers. The at least two adjacent individual layers include multiple adjacent rows of the ballistic paver blocks. The ballistic paver blocks are formed from wet ballistic concrete prepared without an addition of a preformed foam or wet ballistic concrete prepared without an addition of a stabilizing agent.

Systems and methods for recovering bullets from a backstop are disclosed. In one example embodiment of a method, fired bullets and backstop material are collected from the backstop. The fired bullets and backstop material may be vacuumed. The collected bullets are separated from the backstop material based on buoyancy of the collected bullets and backstop material in a liquid. The liquid may have a density that is greater than the density of the backstop material and less than the density of the collected bullets.

A handgun-shot suppressor has a housing with an outer shell with a rear end adapted to fit with a shot-containment device and an opposite front end. A mass of sound-deadening material within the housing forms a passage and is formed at the front end with a front cavity fittable with a muzzle of a handgun so that a shot fired by a handgun fitted to the front cavity passes through the passage. A gas-permeable cover lining the passage and the cavity lies against the mass of sound-deadening material. A rear wall penetrable by the projectile closes the rear end of the housing.
