I got mine from the ammonsource and my 50 round drum from questar. It's a great combo. Sucks it's restricted but I can always buy a cheap ruger 10/22 for camping.
You need to buy the S&W tower kit (BD-S&W-DRUMTK) & a drum magazine (BD-10-22-DRUM or BD-AR15-22-DRUM)The questar drums from blackdog... do you have to buy adaptors? The questar website is confusing... do you remember what you had to order or part numbers? Thanks...

You will have to disassemble the drum and install the tower kit. The instructions are a bit confusing, especially regarding spring tensioning. Take your time and do it right, or the mag will not feed correctly. It took me 2 tries to get the spring tension right. Once I got the spring tension correct, it has been 100% reliable.
So it is a $122 50 round drum... ok.
