It fits the magazine a little bit tight but after some time it loosens up. It is great quality and if the rubber bands holding the pouch onto your belt/vest is treated with care it will last. It's nice and simple and I love that you can stack them! Overall five stars
I have really liked these mag holders a lot not to tight not to loss. I would recommend these mag holders.
Best mag holders I have used yet. Each individual holder is Molle compatible using an included 'n' shaped shaped rubber strap and can also be mounted to the front of another mag holder (front of mag holders not Molle compatible).
They are friction fit, so mags can not be held in a 'pull-down' fashion, but I do not store mags this way anyway. The mag holders work by basically putting rubber bands around two nesting plastic cups. This DOES allow for velco-ed mags to be held. When double stacked the front mag hold can hold a 25 drum.
All in all very easy to attach and use, and very durable.
