I'm interested in building an AR. My buddy built a AR off the Palmetto Arms 80% lower. I'm getting my tax return and am considering building an AR myself. I know there are many of you that have lots of experience. What do you guys suggest? I've done a lot of reading around and varying opinions all over the place. I'll probably get the same here, but I figured I'd ask. Any good sources you can point me to are greatly appreciated.
