DSR-50

The DSR-50 is a bolt-action anti-material rifle developed and marketed by DSR-precision GmbH of Germany, and is essentially an upscaled DSR-1 chambered in .50 BMG (12.7×99mm NATO).

Manufactured by DSR-Precision GmbH, the DSR-50 is based on the DSR-1 sniper rifle and includes modifications necessary to the fire the more powerful .50 caliber round, including a hydraulic recoil buffer in the buttstock and an innovative muzzle attachment. This muzzle device, described as a 'blast compensator', is a combination sound suppressor and muzzle brake, and is notable in its attempt at moderating the .50BMG's muzzle blast and recoil, unlike contemporary large-caliber rifles which are typically equipped with muzzle brakes only. Like the DSR-1, this rifle retains its bullpup configuration, allowing a longer barrel while retaining a shorter OAL (overall length), which is an important consideration for large caliber rounds such as .50 BMG, and focuses the weapon's balance towards the buttstock, compensating for the muzzle heavy attachments standard on the DSR-50. The DSR-50 also retains some of the DSR-1's features, such as a top mounted bipod, monopod, free-floating barrel, fully adjustable cheekrest, buttstock and foregrip, and forward magazine holder.
