So after over a month of waiting, I finally got my AR-15. It's a RRA Tactical Operator 2. I just picked it up over my lunch break, and wow is this thing solid! The first thing I did was give it a little shake to see if there were any loose parts, and the only thing was the screw at the beginning of the buffer tube, so I was able to tighten it a big with my fingers. This is my first AR and I'm very excited to take it out to either my friends house or the range this weekend to shoot. I also noticed that is nicely oiled and looks ready to go. I got a MagPul flip up rear sight for it too. One quick question about the ammo. I bought two different boxes and one box I think were just reloads the that gun store had. They don't have a brand name, just a white box of 55gr .223. Why do they have an orange tip on the end of them? It almost looks like a plastic orange tip. Here are some photos of my new AR, sorry about the crappy quality..taken with a camera phone.
