Maybe short-medium range red dot optics, not a sniper scope. Theoretically BEAR should have mid-long range scope but it's Empires so...
Keep in mind we're talking about empires devs. They have more important things to do than create new content. If it's easy, then sure. If not, then just use the scout rifle scope. The goal is to make the rifle as useful at long range as the BEHR is useful at close range.
It should be possible to put the scope on and add a substantially lower zoom on the optic, as well as having vision around the optic.
