I have heard the term "coyote gun" several times and am curious as to what this is. I would like to build a AR style rifle and thought that a "coyote gun" might be a good first attempt. The maximum range probably won't exceed about 200 yards because of terrain. I'm particularly interested in suggestions for barrel length, scope power range, or anything else that would be helpful. Any assistance would be greatly appreciated. Thanks in advance
