MSG90

http://www.imfdb.org/images/b/b4/HKMSG90.jpg 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 expected accuracy is below 1 minute of arc (MOA) and it is considered to be one of the most accurate semi-automatic sniper rifles in the world. Its accuracy is sometimes even better than a bolt-action rifle. In the hands of a professional shooter, the PSG-1 is capable of putting 50 rounds of match ammunition inside an 80 mm circle at 300 meters (3.14 in circle at 328 yd). The specs listed above are mere factory listings. This rifle is a benchrest gun in autoloader camouflage. Easily capable of 1/2 MOA out to 500 m with factory Gold Medal Match Ammunition and a higher powered optic. (Nightforce 2.5-10x 32mmobj)

All PSG1s are free of iron sights but come mounted with the Hensoldt 6×42 scope with illuminated reticle. The scope has a built-in range adjuster which can be adjusted from 100 to 600 meters, so 600 meters is sometimes considered its maximum range, but it can still in fact shoot out to 1000 meters accurately.

It has a heavy free-floating barrel and adjustable stock. The PSG1 stock is of high impact matte black plastic, which can be adjusted to fit anyone. 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 is adjustable for pull and is removable from the pistol grip. The pistol grip is of a target-type with an adjustable palm shelf.

Another unique characteristic of the PSG1 is that after firing, the cartridge casing is ejected with substantial force, reportedly enough to throw it approximately 10 meters sideways. 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 afterwords, 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 PSG1 also has a fluted chamber that does not allow the use of subsonic ammunition normally used in conjunction with a sound suppressor or built-in silencer.
