SVD:

Learn about the SVD sniper rifle in Metal Gear Solid: Portable Ops, its stats, and how to obtain it in the Western Wilderness.

Adopted by the Red Army in 1963, the SVD sniper rifle in Metal Gear Solid: Portable Ops features a gas-operated mechanism for automatic fire, distinguishing it from the Mosin Nagant. Its ammunition capacity is double that of the 10-round Mosin Nagant, and its accuracy exceeds the NATO standard. This, combined with its repeat-fire capability, allows for sustained suppressing fire against enemies. It uses 7.62x54R ammunition.

Obtained: You can obtain the SVD in Metal Gear Solid: Portable Ops when FOX (an enemy type) appears in the Western Wilderness during alert mode (a status where enemies are actively searching for you). You can find reports on the SVD in the Western Wilderness Report.
