So it took me a little longer than the 12 minute Youtube video I watched, but I finally got my AR put together. Here are some pics: Please keep in mind this is my first build, and just a basic AR. I already have some ideas of what I want to change. For anyone thinking about doing this, its well worth it! I didn't build the upper, just the lower, and it was real easy. All I used was a short two part video off of youtube and printed instructions from AR15.com. I did launch two springs, but heard where they hit and was able to find them. I got to the Takedown pin and couldn't find the detent pin in my pile of parts. I was cussing the person that put the packet together when I noticed something in the end of the buffer retainer. It was the pin and it had some oil in it that kept the pin from falling out. All the parts where there, and went in pretty easy. The only "special" tools I used were a curved set of needle nose pliers, a small tack hammer, and a set of punches. I didn't have these, so $18 at HF bought all the tools I need. One question I do have- Is it normal that when I pull the charging handle back, I have to push it back into place in the receiver? For some reason I was thinking they had a spring and would return back into the upper. Also after, pushing it back in, I have to hit the bolt catch to fire. I've not fired this thing yet, so keep that in mind before you think thats a dumb question. I'm assuming it will work differently when there it is loaded. Thanks!
