The PSG-1 is a semi-automatic Sniper Rifle based on the rifle of the same name. It is designed and manufactured by Heckler & Koch of Germany. In the GTA Series, the PSG-1 is equipped with both a telescopic sight and a red laser point sight. The rifle has a seven bullet magazine, allowing for (brief) rapid firing, in contrast to the bolt-action mechanism of the regular Sniper Rifle.
The HK MSG90 rifle, a Military Variant of the PSG-1, was first featured in Grand Theft Auto: Vice City and is also seen in Grand Theft Auto: Liberty City Stories. The rifle is labeled as the "PSG-1" only in the PS2 Version of Grand Theft Auto: Vice City; all other versions label it .308 Sniper, and it is labeled Laser Sighted Sniper Rifle in Liberty City Stories. It also has a suppressor but serves no purpose other than athstetics. In Grand Theft Auto: Vice City Stories, the MSG90 is replaced by a Dragunov (SVD-1) to fit the game's setting of 1984.
The PSG-1 (not a MSG90) in Grand Theft Auto IV is referenced in-game as the Combat Sniper. It has a ten-round magazine, and excellent range. The reticule used is not a standard mil-dot, but the graduated sight found on the Russian SVD Dragunov's PSO-1 scope. During first-person aiming, if the player is standing, there is a noticeable movement of the scope due to Niko Bellic's breathing. This can be minimized by crouching. The Combat Sniper rifle delivers a one-headshot kill in single player and multiplayer, unless the target is armored. It will also kill with about 3 shots to the body. It can easily take down pedestrians, drivers, motorcylists and, with patience and extreme accurancy, take down helicopter pilots.
