My rifle is getting a MSG-90A1 upgrade and I'm looking for an optic. I want to be able to shoot long range. I looked at some optics yesterday, but about fell over when I seen the $1700 pice tag on the Night Force scopes. Can someone point me to some refurbished optics at a lower price? I really hate to spend more than $400 max. I'm only going to use it for target shooting. I like the Nikon scopes.
