My brother won a AR15 at a raffle with a flat top and no sights. I also recently purchased the same. We are now looking for a scope and need help. We want a reasonably priced scope for shooting 100 to 200 yards, not for TAC team purposes of clearing buildings, just for hitting a coyote not too far away. Hoping there is something in the $100 to $300 range that is decent quality. Any advice?
