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.

What's interesting about the PSG 1 is the accuracy test employed by HK, to know wether they are OK (to be used, shipped out, sold, whatever) or faulty.

You see, A LOT of the times when someone claims to manufacture a sub MOA rifle they shoot 5 shot groups (sometimes even 4 or 3) to "prove" their claim.

Well, HK with it's PSG 1 employs a different (and much more honest) benchmark: 50 rounds in a 8 centimeter circle at 300 meters...which in terms of *pure maths* equals slightly under 1 MOA

Let's do the maths:

1 MOA = 1.047 inches @ 100 yards = 2.659 cm @ 100 yards = 2.909 cm @ 100 meters = 8.727 cm @ 300 meters

8 cm @ 300 meters = 0.917 MOA (therefore, technically speaking, the PSG 1 is at worst a 0.91 MOA rifle...otherwise it doesn't pass the test and gets discarded or something)

And again, keep in mind that all this is established with a 50 (fifty!) round group at 300 meters...

Amazing rifle for sure...

Heckler & Koch PSG1

The PSG1 is a semi-automatic sniper rifle designed by theGerman company Heckler & Koch of Oberndorf am Neckar. This rifle is said to have been developed in response to the Munich massacre at the 1972 Summer Olympics. The West German police units could not engage the terrorists quickly enough to prevent them from killing their hostages. H&K was then commissioned to create a high accuracy, large magazine capacity, semi-automatic rifle for police and military use.

In addition, the rifle has been licensed for local production in Pakistan by Pakistan Ordnance Factories (POF) as the PSR-90 and Mexico by SEDENA as the Morelos Bicentenario.


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.

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.
Versions of HK PSG1
PSG1A1

The PSG1A1 variant was introduced by Heckler & Koch in 2006, and features two major improvements. First, the cocking handle was relocated a couple of degrees counter-clockwise. This was due to the fact that when locked rearward, it often physically interfered with the long scopes often used on the rifles. The second modification involved the replacement of the outdated Hensoldt scope. Non-police users often found the scope’s 600 m range limitation and simple crosshairs inadequate for their needs. In addition, the rechargeable batteries are difficult to recharge and to find replacements. A final fault is that Hensoldt does not service the scope in the United States. For these reasons, the PSG1A1 has been outfitted with a Schmidt & Bender 3-12×50 Police Marksman II scope, mounted on 34 mm (1.3 in) rings. One last modification involved converting the SG 550 Sniper stock to work with the PSG1. The H&K rifle now has a completely side-folding adjustable target stock removing a solid 10 inches (250 mm) in overall length. To remedy brass ejection a brass catcher must be installed.

wasn't Pakistan replacing the PSR-90 with some newer one called "Azb" or am I incorrect?
