In the file "newhud" (1KB ) added a line loadMenu - { ui/xhairs.menu" } 
If you add a file "xhairs" folder "ui" , where lie HUDS and in the game list in the console /cg_crosshairsize 0 and /cg_drawcrosshair 52 or 57 ( and also 22, 27, 32, 37, 72, 77) 
ou will see what crosshairs can change the cross and the cross in a circle.
If something is not clear, follow me QL.
