Here you have few scopes which you may like, as for the rifle model there is a model of the Dragunov as well as models of few other sniper rifles you could use.

i like them allot namely your invited chevron one (and i hate using a chevron system on a normal basis) but i am still looking for a scoped version of the regular semi its mostly aesthetic reasons.
