| Source measurement | The PSG1 is mechanically based on the Heckler & Koch G3 battle rifle that employs a roller-delayed blowback operating system. Its shot-to-shot variation is expected to be better than 1 minute of angle (MOA) with match ammunition. This level of accuracy is only average compared to most modern bolt action sniper rifles, but is still exceptional for a semi-automatic rifle and at one time was claimed to be "one of the most accurate semi-automatic sniper rifles in the world."[source]Heckler & Koch PSG1 · Design details; only the objects and conditions stated in this passage PSG1s are not supplied with iron sights but come equipped with the Hensoldt ZF 6×42 PSG1 scope with an illuminated reticle . The scope has a built-in bullet drop compensation range adjustment feature which can be adjusted from 100 to 600 m.[source]Heckler & Koch PSG1 · Design details; only the objects and conditions stated in this passage 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 because when locked rearward, it could physically interfere 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 The second modification involved the replacement of the outdated Hensoldt scope.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 for which 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. To remedy brass ejection a brass catcher must be installed.[source]Heckler & Koch PSG1 · Design details / PSG1A1; only the objects and conditions stated in this passage | — |
