It is plastic, so the channels that suppose to hold onto the rims of the rounds are not strong/wide enough and can easily bend or brake out of shape. Rounds won't stack and stay in place properly after that, and pretty much it becomes useless at the point.

Didn't need it but got the mag loader just cuz, nice construction and easy to use but sometimes I have a hardtime pushing ammo into mag.

Great quality

I am not quite sure why this loader gets bad reviews. It worked very well for me, loaded six 30-round magazines in a few minutes. The only issue I noticed is getting the last round in, you have to slide another couple of rounds into the loader to push it in.

This is a must have item for rapidly loading your magazines at the range. The APC9 series weapons are so fun to shoot you will want to load mags at the range to continue having fun. Might buy another just as a backup..."one is none and two is one" Regards W

Very poor performing product. Hard to use and the feed lips that held the cartridge rims rapidly became deformed. I would give this a 1 out of 5 rating with1 being poor and 5 being great.
