How sights are specified for a tender
A rifle sight tender states magnification, field of view, exit pupil and eye relief, reticle type and illumination, adjustment range and click value at 100 m, mass, battery life, and the mounting interface, usually a MIL-STD-1913 rail. Reticle distance scales tied to a calibre, as on M20 for 5.56 mm, 7.62 mm and 6.5 mm, should be matched to the weapons in service. For thermal sights the detector resolution, NETD, lens focal length and detection and recognition distances for a human target take the place of optical magnification.
Choosing between optical, reflex, thermal and laser
Magnified optics M10, M20 and NDS X3 are specified by magnification and field of view for daytime use. Reflex sights NR-3 and RS-C are x1 devices listed for day and night conditions. Thermal sight NT-35 is listed for total darkness, haze, dust and vegetation, and NT-75 for machine guns and automatic rifles with photo and video recording, the 75 mm lens giving 2400 m human detection against 1140 m for the 35 mm lens. Laser aimers OCL-4 and OCL-V / OCL-N project a visible or IR aiming dot, and VN-4 adds a separate ocular for observation and aiming from behind cover.
Questions about this equipment
Are the reflex sights usable with night vision?
Yes. NR-3 is listed for day and night use with three night and six daytime brightness levels, and RS-C is described for day, low visibility and night use combined with night vision devices. Both are x1 sights mounted on a MIL-STD-1913 rail.
What is the difference between OCL-4 and OCL-V / OCL-N?
OCL-4 is a dual spectrum device that switches between a visible 650 nm and an invisible 850 nm laser and adjusts both together. OCL-V and OCL-N are single spectrum versions, V visible and N invisible, waterproof to 2 m. All mount on a Picatinny rail, weigh 290 g with battery and run on a CR123 cell.
