7.62x54R
As far as the shooter can see.
The A&K SVD Sniper Rifle (Dragunov) is a Soviet rifle that was introduced in 1958 and accepted in the military on 1969. It is an adaptation of the AK-47 which was made to accurately keep troops at 650 meters. The Dragunov is a semi-automatic rifle chambered in 7.62x54Rmm. The maximum effective range of the Dragunov is 850 meters while the maximum range is 1,300 meters with scope. The Dragunov was designed by Evgeny Dragunov.
First off, I assume that you are talking about magazines, not clips. Neither the SVD Dragunov or AK-47 use clips. The answer is no. The SVD uses a 7.62x54 round, while the AK-47 uses the 7.62x39 round. In basic terms, the SVD uses a larger round and thus a larger magazine than the AK-47.
Snayperskaya Vintovka Dragunova. Translated, would amount to something like "Dragunov's Sniper Rifle".
Dragunov SVD (Russian semi-automatic sniper rifle)
If you mean the SVD Sniper rifle manufactured by the Soviet Union, no, it is not a .50 caliber weapon. It fires a match grade version of the 7.62 X 54R cartridge- the same round used by the Moisin-Nagant 91/30 rifle (and the M38 and M44 Carbines). Wikipedia has a good concise article on the Dragunov sniper rifle. Enjoy.
I recommend going to Ebay or Craigslist to try and find something like that.
There is a rail on the left side of the SVD receiver, all SVD compatible optics fit this rail. You just flip out the locking latch, slide the scope on until it stops and then lock the latch forward. You can also get weaver rail mounts that have this slide.
A genuine Soviet SVD is worth up to $10,000 - usually not less than $6,000. Depending on accessories and shape. Chinese copies (NDM 86) are worth less, about $3,000 to $5,000. The commercial version - Tigr, is worth $2,000 to $3,000. A PSL Romak (often advertised as a "Romanian Dragunov") is not really a Dragunov pattern rifle and a reasonable price is WAY under $1,000.
The Dragunov (note corrected spelling) sniper rifle is in caliber 7.62x54mmR. This is the same caliber at the Moisin-Nagant 91/30 rifle.
The Dragunov SVD came from the Soviet Union. It was manufactured in several Soviet republics, the Peoples' Republic of China (as the NMD-86), and in Serbia (formerly one of the republics of Yugoslavia).
thet depends see you get more damage when you hit someone with the 50 cal but it has horible recoil the dragunov has really good recoil and you can get a golden dragunov my opinion is pick the dragnunov
