Board Thread:General Nerf discussion/@comment-4436775-20131123034933

I'm getting ready for a Nerf war that I'm having, and I've adopted a sniper/spotter style. I need a scope or a sight that gives somewhat accurate measurements, especially for projectile drop. I've tried to work with the flip-up sights on the Longstrike, but often, when I'm correcting for the drop, there isn't enough (mils, as I call them) and I run out of aim. Is there a scope with some accurate measurement that is also easy to find?
