I am buying my first scope that will be dedicated to my three gun AR. I'm trying to keep the costs low as I don't go out of my immediate area for three gun. (It's fun, but it's not an obsession.) Most shooters use either a 1-4 or a 2-7 optic. I'm currently considering the following two which I will link below. But I am open to suggestions. Nikon ProStaff 2-7 x 32 Black Matte Riflescope This is the one that is used by most of my friends. Their selling point is cost. Vortex Optics Crossfire II 2-7x32 Rifle Scope, Dead-Hold BDC Reticle This is priced similarly to the Nikon Prostaff and I like the BDC recticle. So what are your thougths on these optics? Also, what mounts would you suggest for these? I've found mounts priced from $15 all the way up to $250 and I'm not too sure what the difference is on them.
