There are so many choices. I like the new Airmax reticle. That Hawke line is 2-7X32 all the way up to 4-12X50.http://www.hawkeoptics.com/airmax-2-7x32-amx.htmlBut then those Slayer probably wont need much for mil dots. Leopold has the LR Dupex which gives 3 points elevation.https://www.leupold.com/hunting-shooting/scopes/vx-2-riflescopes/vx-2-2-7x33mm/
