Comes with 5 mags, plastic, holds 100 rounds, NO WIND!!!!, little wobble in Echo1 mk5, cheap, and nothing shakes in the mag.
What I use this for is I wanted some cheap mags, didn't want to wind, and I wanted alout of mags.
I was going to get some high caps but i wanted to fill all the mag space on my vest so I got this and got 5 of them, no winding, and holds 500 rounds all together!
1. hard plastic
2. holds 100 rounds!
3. no wind
1. plastic, but not a big deal
