DFX TECHNOLOGY PSG-1 The PSG-1 sniper system (PrazisionsSchutzenGewehr, or "high-precision marksman's rifle") had been developed by the German company Heckler - Koch by the mid-1980s as an ultimate police and counter-terror weapon. Some German elite law-enforcement groups, like GSG or KSK-9, participated in this development, and since its introduction the PSG-1 had been adopted by various police forces in Europe and Americas. It is fairly heavy and somewhat underpowered compared to other sniper rifles, so it has never been selected for military use. Technically, the PSG-1 is no more than a heavily modified G3 rifle. It features the same roller-delayed blowback action, derived from earlier CETME rifles, and the same stamped steel receiver with separate detachable trigger unit. The heavy barrel is made by a cold hammer forging process with polygonal rifling for improved accuracy and longer life. The special trigger unit features a semi-automatic only hammer group and an adjustable trigger with a light trigger pull of about 1.5 kg (3 lbs). The ergonomically shaped pistol grip features an adjustable palm stop. The plastic buttstock is also adjustable for height and length. Another non-typical feature of the PSG-1 is the "silent bolt closing device", actually similar to the forward assist, found on M16 rifles. This is apparently to be used in situations where a complete silence must be maintained until the shot is fired. The device is no more than a pushbutton, located just behind the ejection port, and is linked to the bolt carrier. Ammunition may be fed using either the standard 20-round G3 magazine or a special 5-rounds magazine. There are no open (iron) sights on the PSG-1, instead, it is fitted with a Hendsoldt 6X42 fixed power telescope sight with illuminated reticle. The scope has a built-in range adjuster that works in ranges from 100 to 600 meters. Most strangely, the PSG-1 had no integral bipod. Instead, it is often used with the separate rest, mounted on a compact tripod. Links Manufacturer
