Guys I am building one more AR. The lower is built. Now I am working on the upper in .223. I want to use the build for mostly varmint/predator hunting and some target shooting out to 300 yards. I don't want a huge barrel. I was thinking about a 16" or 20" target heavy barrel. I want to be able to shoot 50gr to 69gr.
What length barrel and twist would be best? I would like to try and stay with a 16" to keep it a bit more compact.
