The PSG1 (Präzisionsschützengewehr, German for "precision-shooter rifle" or "marksman rifle") is a semi-automatic sniper rifle designed by the German company Heckler & Koch of Oberndorf am Neckar.
Design details:-
The PSG1 is mechanically based on the G3 rifle and features a low-noise bolt closing device (similar to the forward assist on many M16 rifles). Its shot-to-shot variation is expected to be better than 1 minute of angle (MOA) with match ammunition. Although this level of accuracy is unremarkable in modern semi-automatic rifles, it was claimed that the PSG1 was "one of the most accurate semi-automatic sniper rifles in the world."[1]
PSG1s are not supplied with iron sights but come equipped with the Hensoldt ZF6x42PSG1 scope with an illuminated reticle. The scope has a built-in range adjustment feature which can be adjusted from 100 to 600 m.
It has a heavy free-floating barrel with polygonal rifling and an adjustable stock. The stock is of high impact matte black plastic and has a high degree of adjustment. It is adjustable for length, and includes a pivoting butt cap and a vertically-adjustable cheekpiece. The forend is fitted with a T-way rail for sling swivel or tripod.
The rifle also features a removable and adjustable trigger unit, for further individual fitting of the rifle. The trigger pull can be modified and the whole assembly is removable from the pistol grip. The pistol grip is of a target-style with an adjustable palm shelf.
Another notable characteristic of the PSG1 is that after firing, the cartridge casing is ejected with substantial force, reportedly enough to throw it approximately 10 meters to the side (SVD rifle also has a similar tendency). While this is generally not an issue for law enforcement snipers, it greatly compromises the military use of the rifle, because it would easily give away the sniper's position. The brass is also difficult to find for clearing the area of usage marks afterwards, due to the wide area in which it could have landed. Not only does this rifle eject brass some distance, but it crimps the casing severely, meaning most casings cannot be reused.

The PSG-1 sniper system (PrazisionsSchutzenGewehr, or "high-precision marksman's rifle"in English) had been developed by the German company Heckler - Koch by themid-1980s as an ultimate police and counter-terror weapon. Some German elitelaw-enforcement groups, like GSG or KSK-9, participate in this development, andsince its introduction the PSG-1 had been adopted by various police forces inEurope and Americas. It is way too heavy and somewhat too gentle for militaryuse, so it never seen any military use. Instead, HK developed two more sniperweapons. The first, that actually preceded the PSG-1, was the G3-SG1, an accurizedand scope-fitted version of the basic G3 automatic rifle for German Army. And inthe mid-1980s HK also developed a derivative of the PSG-1, called MSG-90, forexport military sales. The PSG-1 is still offered by the HK, and is one of themost expensive factory-made sniper rifles on the market, hitting the $10.000price tag in the basic package.
Technically, the PSG-1 is no more than a heavily modified G3 rifle. It featuresthe same roller-delayed blowback action, derived from earlier CETME rifles, andthe same stamped steel receiver with separate detachable trigger unit. The heavybarrel is precisely made by the cold hammer forging process with polygonalrifling for improved accuracy and longer life. Special trigger unit features asemi-automatic only hammer group and the adjustable trigger with trigger pull ofabout 1.5 kg (3 lbs). The ergonomically shaped pistol grip features anadjustable palm stop. Plastic buttstock is also adjustable for height and for lengthof pull. Another non-typical feature of the PSG-1 is the "silent boltclosing device", actually similar to the forward assist, found on M16rifles. This is apparently to be used in situations where a complete silencemust be maintained until the shot is fired. The devise is no more that apushbutton, located just behind the ejection port, and linked to the boltcarrier by the ratchet-like device. The rifle is fed using standard 20-rounds G3magazines or special 5-rounds magazines. There's no open (iron) sights on thePSG-1. Instead, it is fitted with the Hendsoldt 6X42 fixed power telescope sightwith illuminated reticle. The scope has built-in range adjuster that works inranges from 100 to 60 meters, so 600 meters is considered the maximum effectiverange. Most strangely, the PSG-1 had no integral bipod. Instead, it is oftenused with the separate rest, mounted on the compact tripod.
The PSG-1's official silencer is from Brügger & Thomet (B and T).
