h&k msg90
The MSG90 (Militärisches Scharfschützengewehr) is a German 7.62×51mm NATO semi-automatic sniper rifle developed by Heckler & Koch in 1980s as a cheaper alternative to the PSG1. The weapon looks like a scoped G3 rifle with a bipod, an adjustible buttstock and a cheek piece (see Danbooru post #1452271). Unlike the PSG1, it lacks the distinct palm shelf on the pistol grip.
