Finally found a S&W M&P15 that was in stock (2 left ) but it's the OR model, which is fine with me... but now I need to start figuring out what to do to aim the damn thing. Eventually I will get optics for it, either an EOTech or Aimpoint, but to start, I need irons. Give me good ideas. Price range - under $200 for both. I really like Troy battle sights... but my god, $140 for ONE? The gun industry has gone crazy, I swear.
