Tapco 20 round sks magazine how well does it work?

Does it take stripper clips? And how reliable is it? How long does it take to swap mags, instead of using stripper clips( I'll still get stripper clips)? And is for stocks, the tapco 6 position "Intrafuse" or the ATI Dragunov better quality? And what about that folding thing? And how does the folding 6 posioion one work? I love the look of the wooden stock, but it's not as functional. It probably can't take as much of a beating. I don't abuse my guns( In fact, I take great care of all of them), but accidents happen no matter how careful you are... So do the tapco 20 round mags work, and which aftermarket stock is best( excluding the monte carlo)? Thanks!
