||Awesome magazine. I like it more than the metal ones because these are super light.
If you are worrying about these being ABS not metal, keep in mind real MP5 magazines are ABS as well.
Furthermore, I have abused these like they are the real thing and none have failed on me.
I lubricate mine by spraying some silicon oil in the bb loader once every 3 months.
They work as expected, great feeding, stealth and simply does the job.
Light, you can literally carry 50 of these with you without breaking a sweat.
