The barrel is protected by a ventilated aluminium handguard and is fitted with a muzzle brake (which is very useful when firing full-power, magnum loads). The trigger is two-stage and adjustable. The DSR-1 features a manual, ambidextrous three-position safety, located above the trigger guard. For the standard version of the DSR-1 a tactical

is available. The suppressor is designed to be used with high power ammunition of the DSR-1 chamberings. This suppressor effectively suppresses the muzzle blast. Naturally it cannot suppress the crack of a supersonic projectile but the direction where the bullet comes from is effectively concealed. The tactical suppressor is easily mounted in seconds on the muzzle brake using a quick release lever The performed test shoots with a DSR-1 to get an indication of its accuracy potential with factory ammunition in October 2003. The 5-shot groups were obtained by test shooters whilst shooting from the bipod and measured from centre to centre.

region. Whether the DSR-1 can perform better under ideal environmental conditions with handloads tailored to the particular rifle and/or if the human test shooters were a limiting factor was not tested by Visier magazine. An article on the DSR-1 in the French Armes & Tir November 2001 gun magazine corroborates the German Visier results. The Armes & Tir test shooters used RUAG target cartridges and could shoot 200 x 300 mm (0.69 x 1.03

) groups at 1,000 m distance with a Lapua Magnum chambered DSR-1 rifle.

subsonic ammunition usage. The barrel length is reduced to 310 mm. The 8 inch twist rate of the barrel is especially adapted to stabilize the long heavy projectiles used in subsonic ammunition. The propellant charge of subsonic ammunition is reduced to keep the bullet velocity ( below the speed of sound (~ ). At this subsonic speed the supersonic crack that arises when standard ammunition is fired is avoided. The manufacturer recommends exclusive use of subsonic ammunition for the DSR-1 Subsonic. DSR-50
