PSO-1

This telescopic sight is different from the original PSO-1 only in that it lacks the now obsolete infrared detector, which was used to detect generation-zero active-infrared night vision devices like the US M2 Sniperscope.

It features professionally ground, fully multi-coated optical elements, a baked enamel finish for scratch protection, and an attached, quick-deployable, extendable sunshade.

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) increments.

Most modern military tactical scopes with lower power fixed magnification such as the ACOG, C79 optical sight or SUSAT (intended for rapid close-intermediate range shots rather than long-range sniping) lack such features as well.

Modern fixed magnification military high-end-grade sniper telescopic sights scopes intended for long-range shooting usually offer one or both of these features.

The three lower chevrons in the center are used as hold over points for engaging area targets beyond 1,000 metres (1,094 yd) (the maximum BDC range setting on the elevation drum).

The PSO-1 is issued with a lens hood that can be attached to the ocular to reduce/eliminate image quality impairing stray light and a carrying case to protect the sight during transport and storage.

The reticle features a stadiametric rangefinder, ranging out to 400 meters and a single chevron as an aiming point with vertical stadia lines for a windage hold.

This version has a 400 m stadia metric range finder marked 1.7 m. The POSP is a commercial variant which features various reticles, windage/elevation turrets, mounts, magnification, and variations of the body and lenses used.
