Worked better than all others for me! - VISM AR Mag Speed Loader V2

To be frank, I was concerned about this, due to the low-end brand. That said, I ordered several mag loaders all at the same time, some for rifle, some for pistol. This one worked better than all the other rifle loaders I have used- from that order, and in general. Granted, I have not used nearly all of them, however, this one worked great for me!
I use it for .223. I found that due to the design, it lines up the rounds perfectly, and the boxy design helps the rounds stay lined up during feeding, which helps load the mag properly, and fast.
No mess, no rounds flying everywhere, no f-ing with it trying to get it to work. I just read the instructions, followed them, and it works great!
I had zero learning curve with this, unlike several other designs which take some practice and getting used to.
I wish they would make one for pistol rounds!
