DSR – ТЕХНОЛОГИЧНО НАЙ-ДОБРАТА ПУШКА В СВЕТА.

 
                                  
Най-добрата снайперска пушка в света се произвежда от фирмата DSR-precision GmbH в област Baden-Württemberg  Германия,в малкото градче Alpirsbach, намиращо се на 100 тина километра югоизточно от  Stuttgart. Оборудвана струва 10 000 паунда и при добри условия, е способна да произведе точен изстрел на 2500 метра. В производство е пусната през 2000 година, а от 2004 вече на въоръжение в немските и някои полицейски служби в Европа. Оборудвана е с хидравлична система за поемане на отката и се захранва с муниции .338 Lapua Magnum, а също с  .308 Win. и .300 Win.Mag.

The 5-shot groups where obtained by test shooters whilst shooting from the bipod and measured from centre to centre. The table shows that with target factory ammunition the DSR 1 performs in the 0.34 – 0.63 MOA region. If the DSR 1 can perform better under ideal environmental conditions with to the particular rifle tailored handloads and/or if the human test shooters are 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

ВАРИАНТИ:

The DSR 1 Subsonic is a DSR 1 variant.The DSR 1 Subsonic is adjusted to use the subsonic type of ammunition calibre 7.62x51mm NATO/.308 Winchester. Barrel length is 310 mm. The 8 inch twist rate of the barrel is especially adapted to stabilize the heavy projectiles of subsonic ammunition. This ammunition has the same dimensions like standard ammunition of the same calibre. The propellant charge is reduced to keep the bullet velocity (app. 320 m/s) below the speed of sound (340 m/s). This avoids the super sonic crack of standard ammunition. No type of suppressor can reduce the supersonic crack of a bullet flying at supersonic speed. Only use of subsonic type of ammunition is recommended.

The DSR-50 Sniper Rifle is an enlarged variant of the DSR 1. It has an integrated hydraulic recoil damping system in buttstock and a blast compensator. The blast compensator is a linear compensator or a forward venting muzzle brake that also reduces the perceived muzzle blast. The DSR 50 Sniper Rifle is chambered for the .50 BMG (12.7x99mm NATO) cartridge that is significantly larger than the .338 Lapua Magnum cartridge, which is the biggest available chambering for the DSR 1 rifle. Sniper rifles chambered in .50 BMG are often employed as anti-materiel rifles.
