Piece of junk - MDT .308, 10-Round, Poly-Metal Rifle Magazine

Biggest piece of junk mag ive ever bought, wouldnt feed or eject, i spent 45 minutes playing with my mag height adjustment on my chassis and still would either shove the next round up into the shell trying to be ejected causing it to be prematurely pulled from the bolt and drop in the action or would either be too low and would fall out of the rifle for some reason, about every third round it would bind and shove the loaded round straight down in the mag
