"The PTR-91 is one of a family of modern civilian semi-automatic rifles based on the design of the G3. A larger default magazine size than the Saiga can give you that extra edge you need."
— In-game description
The PTR-91 is a purchasable semi-automatic sniper rifle for the Professional kit, costing $3,300 to unlock. The PTR-91 is equipped with a JGM-4, Suppressor, and Extended Magazines by default. It handles similarly to the Saiga .308, but has more recoil. However, it has a larger standard magazine capacity and its default Suppressor can be useful to a stealth-minded Professional player.
