I'm in the process of getting a custom build AR style rifle (.223) and it will be primarily for coyote calling. Shots range from 10 yds to 300. I rarely take 300yd shots without a very steady rest, so most shots will be under 200yds. I want a scope that permits quick target acquisition and the best visibility possible. I've blown shots where the coyote was close, but I forgot the scope was set on 12X and was gone before I could make adjustments. I'll mostly be shooting off a tripod or bipod. My budget can hopefully be under $500. I've read some about scope options, but want to hear from you guys out there who have experience and needs similar to mine.
