Yes anyone that has never fired a AR, please do. I seriously recommend it. I enjoy shooting all of my different guns, but shooting my 2 ARs are in a whole different category of experience. I seem to love them more every time I take them to the range.
Selling a S&W AR for $699 is a great service. That's quality (they'll work. S&W doesn't make junk), for an affordable price.
I was going to respond to someone's post earlier when they mentioned that they had their 22lr rifle look similar and it was non restricted. I have a sr22 that feels like an AR and has AR furniture on it, but i'm sorry it doesn't compare, cause it doesn't shoot 5.56. The wonderful 5.56. It's loud, fast, has little recoil (which a brake will practically eliminate), very accurate.
I enjoy shooting my sr22 a lot, but if I had a choice: I would just shoot my ARs all day, every day, all the time (between eating and sleeping)
