I went on HBO's website, and found that you can watch the first show, free, online. I had to register, email and password I think, and I didn't mind. I have a middle grade, high speed connection, and had to pause the show and take a brake a couple of times, because the show couldn't load faster than I could watch. Not a big deal to me, it was free.
I did not pause or rewind looking for A3 parts, and I think once I seen a A3 rear sight and maybe a A3 upper band a time or two. Still, you have to look. It wasn't as bad as I thought.
I completely agree with Tom. Everything "looks" OK. Good show! Now I just have to figure out how I'm going to watch the rest of the series!
