The Mini 14 hasn't been working out for me in the accuracy department. I am very familiar with the 223/5.56 but the accuracy of the Ruger is inadequate for my jack rabbit and coyote safaris here in the Mojave.

So, I purchased a stripped AR lower. Now, I need to plan the build of my new "erector set" and have a few questions.

1. For varmint hunting, will a 20" bbl be superior to a 16"?

2. With a heavy bbl would I be able to keep the weight to 7 pounds or less?

Thanks for answering these questions. I need to learn a lot about the AR as this will be my first one. I hope to spend $500 on the entire project.

Thanks!
