The '''PU scope''' (ПУ, прицел укороченный, 'Scope short-cut' in comparison to [[Mosin–Nagant#World WarPE IIscope|PE/PEM telescopic sight]]) is a 3.5×21 [[telescopic sight]] of [[Soviet Union|Soviet]] manufacture, widely used since 1940 on the [[SVT-40]] rifle for which it was originally designed and since 1942 on the [[Mosin–Nagant]] rifle. Before converting the PU for [[Mosin–Nagant#Russia/USSR|Mosin–Nagant Model 1891/30 sniper rifle]]s these rifles used 3.87×30 PE(M) telescopic sights, a Soviet-made copy of a German [[Carl Zeiss AG|Zeiss]] design, while later rifles used smaller, simpler, and easier-to-produce 3.5×21 PU telescopic sights.<ref>[https://www.m9130.info/pe-and-pem-sniper-scopes PE and PEM scopes. General overview]</ref> The PU telescopic sight has a fixed at 3.5 power magnification. The reticle could be adjusted vertically for range, and the elevation turret is graduated from {{convert|0|-|1300|m|yd|0|lk=on|abbr=on}} in {{convert|100|m|yd|0|lk=on|abbr=on}} increments. The [[Telescopic_sight#Bullet_drop_compensation|bullet drop compensation]] (BDC) adjustment in the elevation turret is free spinning under grease friction. The windage adjustment turret of the telescopic sight features more conventional click adjustments in [[milliradian]] increments.

ItWhile isit has been claimed{{who|date=July 2022}} that theSoviet Sovietsoptical instrument makers attempted to create a 6× version of the telescopic sight though, this has been refuted. An aftermarketafter-market objective lens, known as the PU Magnifier (''PUM''), is able to give the PU telescopic sight a 6.5× power.
