Although the AN/PVS-4 has not had a great deal of cultural impact, its legacy of high quality night vision has become a staple of movies and television shows which often do not show real equipment.
The scope base is the attachment interface on the rifle's receiver, onto which the scope rings or scope mount are fixed. Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.
The scope body is sealed and filled with nitrogen, which prevents fogging of optics and was designed to function within a -50 °C to 50 °C temperature range. For zeroing the telescopic sight the reticle can be adjusted by manipulating the elevation and windage turrets in 5 centimetres (2.0 in) at 100 metres (109 yd) (0.5 mil or 1.72 MOA ...

When flipped to the side, the magnifier may also snag on obstacles.
