This is "The High Road" so I'm not going to cast doubts upon any of your statements.
LOL that's the only thing you have done. I didn't try to change the Yugo because I didn't want it to take detachables even if they did work. And I know what I've heard. You don't know what I've heard. And I've seen hundreds of USA brand mags and never once did I see one that needed work before it would function.
You seem to be an expert on all of this but you are clearly wrong about a lot of things. But I wouldn't cast doubt on any of the things you say. You do a fine job of that yourself. And BTW I make my living with words. Maybe the problem is that you can't read.
Mostly you're just a troll though. So goodbye troll. I feel sorry for anyone that takes advice from you.
