I need advice on parts for a build. My wife has a coyote problem where she's living in Oklahoma. So she wants a rifle to deal with said problem. I'm new to the AR game. So I really don't know which manufacturers are quality, which are garbage, etc. Here are my requirements: - 2.23 / 5.56 - as light-weight as possible - An M4 style collapsible stock - I would like to start with a complete lower - Ambi charging handle and if possible magazine release - Short varmint barrel - Light weight! - Low profile quad rails - Did I mention light weight? - Ergonomic pistol grip Also are there any lights I can mount to it which will put a beam out to 200 yards or so, or is this too tall of an order? This is a pretty high priority. Would like this finished within a month or so. I think that's everything... Thanks for the help.
