Depends on which 15-22 we are talking about. The basic model can be had for about $420 new, the magpul one is about $550-$575 depending on location. I have a couple air rifles as well, that I used for the purpose I bought them for and now they sit idly by doing nothing and I always shoot my .22's. If you're gonna use it, then it's a roughly fair deal if it isn't worn out.
A good plan executed today is better than a perfect plan executed at some indefinite point in the future.
