Was wondering if anyone else here uses a red dot sight on their M4 style AR for called coyotes. I hunt in east central Ohio and cover is thick hardwoods with open crop fields and hay fields. Most shots are 150yds. or less. I see most use some variable power scope, but I use my Burris XTS Speeddot sight on my RRA M4. True both eyes open shooting seems to work out good, plus my rig is pretty light. I am going to put together an RRA 20" varmint model with a Burris FFII 4.5x-14x scope over the next few months.
