A method for retrofitting a preexisting wall to include bullet resistance. The retrofitted wall incorporates ballistic paver blocks that are capable of augmenting either an interior or exterior wall. The flexibility gained by using ballistic paver blocks affords cost and weight savings over traditional concrete, or alternatively, metal shielding.

A plate-type bullet trap provides an adjustable angle upper and lower plate system which facilitates adjustment of the individual angles of each plate as well as the mutual and relative angles between the plates. In this manner, the geometry presented by the plate-type bullet trap system may be varied to present a maximized efficiency and effectiveness of the plate trap geometry for various entrance paths and characteristics for bullets and other projectiles.

A shooting range including a shooting station positioned at one end of a firing lane. A projectile trap is disposed at an opposite end of the firing lane for collecting projectiles fired from the shooting station. The projectile trap comprises a deceleration chamber defined by a first scroll wall and a second scroll wall for dissipating kinetic energy of the projectiles and a funneling portion for directing projectiles into the deceleration chamber. The first scroll wall is curved and has a concave surface. The first scroll wall is positioned so that the concave surface of the first scroll wall generally faces in a direction towards the shooting station. The first scroll wall comprises a steel body substrate and has an enhanced impact resistant portion. The enhanced impact resistant portion has an impact resistant layer comprising a plurality of ceramic particles and a binding material bound to a forward facing surface of the steel body substrate.
