I picked up my S&W M&P 15 Sport today. This evening I took it to the range to try it out. The sights were right on out of the box (at least as far as my limited skill would allow). I'm looking forward to taking it out again soon. I can see that my old-man eyes will be the limiting factor for the open sights.
Finished I Am Radar a couple of days ago. I just started Bill Bryson's The Mother Tongue: English and How It Got That Way. It's pretty interesting. I am continually amazed at Bryson's ability to learn so much about the subjects he covers.
