I've looked at those other conversions as well, and honestly, i am completely in love with the idea of shooting my AR without counting the price every time i pull the trigger, but now im starting to think, why pay $200 for a bolt, when i could just go spend $20 on a 30 round mag for my Remington 597.... haha, I'm still considering a conversion bolt, but untill i have a useless $200 sittin around, ill spend it on some .223 or a crapload of .22s :mrgreen: . I have heard that some people have feed problems with the conversions too, anyone know about that?
