I came acrossed these mags last week and i would like to know more about them. Like who makes them and if they are reliable. The only thing i could find after an hour of searching here and the rest of the web was a blog showing a guy using them but it was from 2010 and there was very little info on them. Here is the link Magazines for .22 conversion of HK G3/PTR91 - Oleg Volk
I will post some pics of the ones i have. I cant seem to find any markings to id them.
