Gun ports fitted to a wall of a building or vehicle each comprise an expandable aperture that accommodates penetration from within by a gun barrel having irregularly shaped attachments. The gun ports can provide protection against laser pointers used in training exercises, where lasers are used outside the gun ports by attackers against those protected behind the gun ports. Each implementation of a gun port can accommodate guns of different sizes and shapes. The gun ports can be configured as exchangeable cartridges or subassemblies that can readily replace regular non-expandable apertures otherwise used for defense against real ballistic weapons and explosives. Each expandable aperture expands and contracts as necessary to fit sizes and shapes of a gun barrel portion inserted through it. Of special importance is accommodation of a laser sensor module attached near the firing end of a gun. A window for sighting the gun is provided.

1. A gun port assembly comprising: a. a shoot port cartridge comprising an aperture between two opposite sides of the cartridge;b. a gun comprising a barrel extended through the aperture, wherein a muzzle end of the barrel is located on a first of the two opposite sides, and the end of the barrel opposite the muzzle end is located on a second of the two opposite sides;c. one or more laser detection and/or emission accessories attached to the gun barrel on the first of the two opposite sides; andd. an aperture frame supporting multiple fingers, leaves, or bristles that each extend substantially radially inward from the frame toward a central region of the aperture; wherein the fingers, leaves, or bristles deflect to accept insertion of the gun barrel and its one or more laser detection and/or emission accessories into the aperture; and wherein the fingers, leaves, or bristles are configured to eliminate gaps that could allow laser beam light from directly penetrating the aperture. 2. The gun port assembly of claim 1, wherein the fingers, leaves, or bristles are tapered to narrow as their extension progresses toward the central region of the aperture. 3. The gun port assembly of claim 1, wherein the one or more laser detection and/or emission accessories attached to the gun barrel remain attached to the gun barrel whenever the gun barrel is inserted through the aperture or removed from the aperture. 4. The gun port assembly of claim 1, wherein the fingers, leaves, or bristles deflect far enough to permit passage of the one or more laser detection and/or emission accessories attached to the gun barrel, wherein the one or more laser detection and/or emission accessories attached to the gun barrel may extend sideways from the gun barrel a distance equivalent to more than one diameter of the gun barrel. 5. The gun port assembly of claim 1, wherein the aperture is configured to open or close as a gun barrel is inserted into the aperture or withdrawn from the aperture, respectively. 6. The gun port assembly of claim 1, wherein the fingers, leaves, or bristles are hinged from the frame. 7. The gun port assembly of claim 1, wherein the fingers, leaves, or bristles bend as necessary to track contours of the gun barrel and one or more laser detection and/or emission accessories attached to the gun barrel. 8. The gun port assembly of claim 1, wherein each finger comprises two generally co-parallel surfaces bounded by edges of the finger. 9. The gun port assembly of claim 1, wherein each finger or bristle is circularly symmetric in cross-sections perpendicular to its own axis of elongation. 10. The gun port assembly of claim 1, wherein at least some of the fingers, leaves, or bristles can remain undeflected for at least some positions of the gun barrel. 11. The gun port assembly of claim 1, wherein the fingers, leaves, or bristles are made of a plastic material. 12. The gun port assembly of claim 1, wherein not all the fingers, leaves, or bristles are anchored to the frame in a single plane. 13. The gun port assembly of claim 1, further comprising multiple aperture layers each configured generally co-parallel to a plane defined by a front surface of the frame. 14. The gun port assembly of claim 1, wherein the fingers, leaves, or bristles are not specularly transparent. 15. The gun port assembly of claim 1, wherein the gun barrel is that of a firearm. 16. The gun port assembly of claim 1, wherein the frame is configured to be interchangeable with at least another frame. 17. The gun port assembly of claim 1, further comprising a window through which a person shooting the gun can track a moving target. 18. A gun port comprising: a. a cartridge comprising an aperture; andb. a gun barrel extended through the aperture, wherein one or more laser detection and/or emission accessories is/are attached to the gun barrel; wherein the cartridge comprises a removable frame supporting multiple fingers, leaves, or bristles that each extend substantially radially inward from the frame toward a central region of the aperture; wherein the fingers, leaves, or bristles are tapered to narrow as their extension progresses toward the central region of the aperture; wherein the fingers, leaves, or bristles deflect to accept insertion of the gun barrel and its one or more laser detection and/or emission accessories into the aperture; wherein the one or more laser detection and/or emission accessories attached to the gun barrel remain attached to the gun barrel whenever the gun barrel is inserted through the aperture or removed from the aperture; and wherein the fingers, leaves, or bristles are configured to eliminate gaps that could allow laser beam light from directly penetrating the aperture even as the gun barrel and its attachments are inserted or removed from the aperture. 19. The gun port of claim 18, wherein the aperture fingers, leaves, or bristles are arrayed circumferentially about an axis along which the gun barrel penetrates the aperture. 20. A method of using a gun port comprising the steps of: a. providing a gun port comprising: i. a cartridge comprising an aperture; andii. a gun barrel extended through the aperture, wherein one or more laser detection and/or emission accessories is/are attached to the gun barrel;wherein the cartridge comprises a removable frame supporting multiple fingers, leaves, or bristles that each extend substantially radially inward from the frame toward a central region of the aperture;wherein the fingers, leaves, or bristles are tapered to narrow as their extension progresses toward the central region of the aperture;wherein the fingers, leaves, or bristles deflect to accept insertion of the gun barrel and its one or more laser detection and/or emission accessories into the aperture;wherein the one or more laser detection and/or emission accessories attached to the gun barrel remain attached to the gun barrel whenever the gun barrel is inserted through the aperture or removed from the aperture; andwherein the fingers, leaves, or bristles are configured to eliminate gaps that could allow laser beam light from directly penetrating the aperture even as the gun barrel and its attachments are inserted or removed from the aperture;b. withdrawing the gun barrel from the aperture without detaching the accessories from the gun barrel or disassembling the rest of the gun port. 21. A method of using a laser-defense gun port comprising the steps of: a. providing a gun port comprising an aperture covered over at least partially by flexible fingers, leaves, and/or bristles;b. exchanging a ballistic-defense gun port with said laser-defense gun port; andc. inserting a portion of a gun barrel, and laser detection and/or emission devices attached to the outside of the gun barrel, through the laser-defense gun port.
