Speed loading ammo From SKS stripper clips to AK mag

This Red Star Chinese adaptor slips over an AK mag and allows you to quickly load your magazine using SKS stripper clips. Useful if you only have one or two AK mags and your ammo is on stripper clips carried in a Chinese 200 round chest pouch. WHERE TO GET? I bought mine at a local gun show a number of years ago. I searched the web and here is one place you can get one- only about $5 http://dpharms.com/ak47-speed-loader-p-305.html
