The PSG-1 is said to be the most accurate semi-auto in the world. There is a lot of other rifle manufacturers that will dispute this, but the PSG-1 has become the standard that the others must meet. The accuracy standard that all PSG-1’s must meet is 50 rounds of match ammo into an 80mm (3.14″) circle at 300m. (1 MOA). Keep in mind this is 50 rounds, not a 3 shot group. The PSG-1 is popular in some Special Op units and elite anti-terrorist units. It really does not lend itself well to the Military environment because of 2 reasons. First it ejects the shells about 10 meters, and this can easily give away a position, and also is a pain to try and police your brass to prevent leaving a target identifier. The second reason is that it only can be fitted with the Hensoldt 6×42 sight. No other sight can be used (Short of grinding off the mount and welding on your own type base). The 6x is only set up to be used out to 600 meters, and that is the start of the optimal engagement range for military snipers (From 600-700 meters). Rumor has it that H&K is addressing this problem and have came up with a different system that allows you to switch out scopes, but I haven’t seen one of their new PSG-1’s to confirm this. It is an outstanding Police Sharpshooter weapon, but most agencies cannot afford the price tag (about $15,000 USD on the used market), which is why it usually shows up in only the most elite units.

You may be able to find the missing parts and pieces, but the PSG-1’s also had some reinforcements added to the sides of the frame to stiffen them up for better accuracy. Plus different barrels, etc. I’m not sure you would be able to get it to be an exact PSG-1, and it’d like be expensive. But it certainly doesn’t hurt to add upgraded parts to your HK91.

You could, however ( the sum of all parts plus labor would cost more) and then you’d only have a faux PSG 1 with little collector value ( it would depend on what you want out of your rifle ) .. What is commonly misunderstood , is that the PSG1 is more then an accurized 91 .. its not only the heavier barrel , heavier build internally – trigger group and stiffeners welded onto the frame ..its also a redesign of the HK roller lock which on the PSG are not rollers at all … This is key to the lock up and why the PSG is more consistent in repeatable accuracy .. The PSG uses cams instead of round rollers -( yes they call them rollers – but they are cams , they have a flat -I know I own a PSG 1 ) using a cam ensures that the bolt will lock up at the same point every time , the flats are like flutes on a bolt , indicating on a milled flat surface – using a roller ( which would roll , turn – the lock up point could be anywhere along the circumference ..and with the slightest wear will not be as consistent – the rollers also lock with in a concavity which also is subject to more wear as it is a rolling surface .. Secondly which isn’t a big deal are the optics , although the optics on the PSG are dated , they had 12 set points , pre set out to 600m , Personally I’d modernize the optics as I have done with mine . Best of luck !
