Bullet containment trap with a modular backstop

A bullet containment trap device (1) with a modular backstop (7), wherein the device (1) comprises of:

• at least one electronic target assembly configured to project at least one target placed at a rear end of an open-ended bullet receiving chamber;
• the bullet receiving chamber (4) is supported by a plurality of supporting frames (2, 3);
• the said bullet receiving chamber (4) is backed with a bullet's deceleration chamber (5) in a horizontal axis and or in a vertical axis;
• the bullet fired compasses the bullet receiving chamber (1) while in contact with a plurality of boundary walls and enters a terminal part of said boundary wall over a throat (6) of a passageway and moves through said throat (6) to dissipate on hitting a modular backstop (7) of the said deceleration chamber (5);
• Characterized in that
• the said modular backstop (7) comprises a first impact zone (13) circumferentially oriented at a first angle from the horizontal zone of bullet travel and extends to at least one successive impact zone (14);
• the said modular backstop (7) with at least two impact zones are made by stacking multiple individual armored plates (12) vertically and/or horizontally in to a plurality of cassettes (11);
• the said cassettes (11) formed by stacking multiple individual armored plates (12) are held vertically and/or horizontally to form the said modular backstop (7), wherein the said cassettes (11) are joined with long bolts (8a) making the impinging loads of the bullet hitting the said backstop (7) distributed to multiple individual plates (12) of the said cassettes (11) closely stacked;
• and
• the said cassettes (11) and/or the individual armored plates (12) within each of the said cassettes (11) are all replaceable for deformation.
