The MSG90 was developed as a cost effective alternative to the PSG-1, it has the same operating system and trigger. It features an adjustable stock, but not as fancy as the PSG-1 and it weighs 3 pounds less. The MSG90 makes a great designated marksman rifle (DMR), and in fact, the USMC evaluated 6 of them for their DMR contract. Ultimately the MSG90 was ruled out because it was not retrofitable to .300 WM.

The MSG90 can be expected to shoot sub 1-MOA with good ammo.



The MSG90A1 is the current model in production, though not available in the U.S.. Parts are available for a reasonable clone to be built (this is what I did) or by conversion of current rifles in production such as the PTR91. Either way you’re looking at about $6000+ as some unique original HK parts (trigger group $2000 @ HK Parts)are difficult to find…
