I was working on my dasher today and was having feeding issues with my converted MDT mags. The round was poping up in the rear before the round started in the chamber causing it to jam. I tried a friend's MDT mag and it worked perfect. Looking closely we realized that the front of my feed lips are angled and his were not. I can't seem to find the same MDT AICS without the angled feed lips. My mag it the one on the top and his is on the bottom. Anyone know where to get these?
