The Heckler & Koch PSG-1 is a German sniper rifle created by Heckler & Koch in mid-80s as a HK G3 sniper variant.
The PSG-1 sniper system (PrazisionsSchutzenGewehr, or "high-precision marksman's rifle" in English) 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-9 or KSK, participate in this development, and since its introduction the PSG-1 had been adopted by various police
forces in Europe and Americas. It is way too heavy and somewhat too gentle for military use, so it never seen any military use. Instead, HK developed two more sniper weapons. The first, that actually preceded the PSG-1, was the G3-SG1, an accurized and scope-fitted version of the basic Heckler & Koch HK G3 automatic rifle for German Army. And in the mid-1980s HK also developed a derivative of the PSG-1, called MSG-90, for export military sales. The PSG-1 is still offered by the HK, and is one of the most expensive factory-made sniper rifles on the market, hitting the $10.000 price tag in the basic package.
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 precisely made by the cold hammer forging process with polygonal rifling for improved accuracy and longer life. Special trigger unit features a semi-automatic only hammer group and the adjustable trigger with trigger pull of about 1.5 kg (3 lbs). The ergonomically shaped pistol grip features an adjustable palm stop. Plastic buttstock is also adjustable for height and for length of pull. 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 devise is no more that a pushbutton, located just behind the ejection port, and linked to the bolt carrier by the ratchet-like device. The rifle is fed using standard 20-rounds G3 magazines or special 5-rounds magazines. There's no open (iron) sights on the PSG-1. Instead, it is fitted with the Hendsoldt 6X42 fixed power telescope sight with illuminated reticle. The scope has built-in range adjuster that works in ranges from 100 to 60 meters, so 600 meters is considered the maximum effective range. Most strangely, the PSG-1 had no integral bipod. Instead, it is often used with the separate rest, mounted on the compact tripod.
