The DSR-Precision DSR-50 is a German bolt-action anti-materiel rifle.
Very little is known about the production of the DSR-50; the DSR-50 was designed after 2000 as it is heavily based on its smaller brother, the DSR-1, which was produced starting in 2000. Both weapons are designed by Ingolf Reuter.
The DSR-50 is very much like a bigger DSR-1 chambered for the much more powerful .50 BMG cartridge, and also features modifications which allow it to handle the sheer power of said cartridge. The DSR-50 has a unique muzzle attachment known as a blast compensator, a combination of a suppressor and a muzzle brake. Unlike most muzzle brakes on similar rifles, the blast compensator is actually very effective in reducing the recoil of the DSR-50. The buttstock has a small monopod at the rear and has a hydraulic buffer to help reduce felt recoil. Its bullpup configuration allows it to have a shorter overall length whilst retaining a full-length barrel. Most of the weight is focused towards the rear of the weapon, mainly owing to the massive muzzle brake up front or the blast compensator if attached. While it does appear that the weapon feeds from in front of the pistol grip, the magazine well is actually positioned behind the pistol grip, making it a bullpup weapon; the cavity in front of the pistol grip is actually a magazine storage space.
- The DSR-50 famously appears in the video game Call of Duty: Black Ops II as the DSR 50; it is the most powerful sniper rifle in the game, owing to its massive chambering.
