I've been looking into building a "varmint AR" recently and have noticed almost every time the word "varmint" is associated with any rifle a bull barrel is involved whether it be a bolt action or AR alike. I understand the bull barrel has some benefits with heat dispersal when burning through a lot of ammunition, but to the typical varmint hunter is hauling the extra weight really needed? I'm not talking shooting prairie dogs from a bench all day but more hunting groundhogs and coyotes. I'm asking if heavy bull barrels on varmint rifles is just a fad lately and not at all a necessity? I'm just a little confused on the subject. Someone recently posted about a pencil profile 20" at barrel and it intrigued me to get away from the norm of the bull barrel on varmint rifles. Thoughts from the high road?
