Apparently you are not aware that some of us collect magazines. The post has some info as to manufacturers and approximate dateline of usage.
It is not intended to be a Consumer Reports of "What's Hot and What's Not".
If you wish, you can ask the mods to move this post to the Military Rifles section. Since it was more concerned with mags than rifles, I put it in the Magazine forum. It's your choice where you want it posted.
