King Arms M4/M16-type Midcap Magazines, Black, Set of Six

These are high-quality magazines, very hard, heavy ABS. I tested them Classic Army M4-type guns and with Umarex Tavor TAR-21, and they fit very well. The capacity is about 90 rounds. I test-fired them on the backyard and used them in one game, maybe not even all of them, so they are practically new. Some have silicon oil dried on them, and some look like new (see photos). No scratches, dents, or other signs of use.
