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.

The sighting system utilizes the multipurpose Weaver rail system rather than the STANAG 2324 claw mount for affixing sighting systems which can be purchased separately. This same rail mounting system is used on the HK21E, HK23E, and G41 (discontinued) series.

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 barrel is weighted at the muzzle to aid harmonic stabilization of barrel whip to enhance accuracy. The addition of a flash suppressor adds to the overall length. Mexican produced MSG-90's feature a slightly longer barrel (1.1 inch) and the addition of a built in bipod, although it can be removed with the included tools.

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.

The MSG90 is a militarized variant of the Heckler & Koch PSG1, that is both strengthened and lightened. The PSG1 and MSG90 share the same trigger group and adjustable trigger pull. The composite shoulder stock of the MSG90 is adjustable for height (cheek), length of pull (shoulder), and is smaller and lighter than that of the PSG1. Some MSG90s have a basic G3 barrel instead of the PSG1's heavy barrel, but remain free-floating. As a result, these particular MSG90s are capable of attaching a suppressor, which is an advantage over the PSG1.

The sighting system utilizes the multipurpose Weaver rail system rather than the STANAG 2324 claw mount for affixing sighting systems which can be purchased separately. This same rail mounting system is used on the HK21E, HK23E, and G41 (discontinued) series.

The barrel is weighted at the muzzle to aid harmonic stabilization of barrel whip to enhance accuracy. The addition of a flash suppressor adds to the overall length. Mexican produced MSG-90's feature a slightly longer barrel (1.1 inch) and the addition of a built in bipod, although it can be removed with the included tools.
