I actually decided on the S&W 15-22 because I own an AR-15 and was looking for a cheaper way to practice with it. The 15-22 is almost the same as a standard AR-15 in the way that it functions and breaks down. Safety, charging handle, magazine release are all the same location and function as an AR so it is an economical way to stay in practice. If it wasn't for that, I was going for a GSG as I think that's incredibly cool. My friend bought a laser sight, scope, and fore grip for his which adds a little to the fun factor.
