Bullpup weapons receive their name by shifting the magazine feed and internal action aft of the pistol grip and trigger region. This affords a typically long gun a shorter overall length while preserving its original barrel length, making it easier to handle and transport, and retaining full combat effectiveness. The bullpup weapon has been around for decades but has very recently been growing in popularity for frontline standard-issue weapons across many designs - including sniper rifles.
The German-originated "DSR-1" is one of a number of growing examples concerning bullpup-arranged sniper rifles. As expected, it seats its action and magazine well-behind the pistol grip and is formed as part of the shoulder stock. The receiver is well-streamlined and the barrel is made free-floating for accuracy - the assembly touches no part of the stock along its length. A folding bipod assembly is attached to the upper section of the forend and supports the frontal region of the weapon. The forend consists of a heavily-slotted hand guard which adds barrel cooling. A modest, multi-slotted muzzle brake is fitted over the business end of the rifle. The receiver top supports various optics fits and features a quick-detach function (rail sections are fitted over the receiver and over the forend for tactical accessories). Unloaded and sans its scope, the rifle weighs a manageable 13 pounds, sports an overall length of 39 inches and a barrel length of 25.5 inches. The shoulder stock and cheekpiece are adjustable to the firer's requirements.
The DSR-1 is available in three chamberings - .308 Winchester, .300 Winchester Magnum and .338 Lapua Magnum. Its function is the same across all three types - managed through a manual bolt-action system typical to precision weapons. The handle is set over the right side of the frame in the usual way. Effective range of this sniper rifle is 800 meters to 1,500 meters out largely depending on the ammunition type used. In any case, feeding is from a 5-round detachable box magazine. Another 5-round magazine can be installed forward of the pistol grip in what amounts to a holding area for quickly-accessible ammunition - the shooter need not fumble around for his next magazine.
The DSR-1 comes in a base rifle form as well as two distinct model offshoots: DSR-1 "Subsonic" and DSR-50. The former relies on subsonic ammunition (7.62x51mm NATO / .308 Winchester subsonic) to produce a "silenced" weapon for clandestine operations (the charge of the cartridges is reduced to keep the bullet subsonic). The latter is nothing more than a dimensionally larger version of the DSR-1, the weapon enlarged and reinforced to fire the massive .50 BMG rifle cartridge for use in the Anti-Material Rifle (AMR) role.
Despite the glut of rifles available to snipers in the current global market, the DSR-1 has found a permanent home with a few notable operators - Denmark, Germany, Luxembourg, Malaysia, Spain and Taiwan, usually issued to police sharpshooters or special forces elements. The latter is the case with Malaysia and their PASKAL force, akin to the United States Navy SEALs group.
