These mags look very good ad they look like they would be very high quality mags. That's the thing, the looks are nothing but a trick. The performance of the mags themselves is a 0 out f ten. I bout 2 of the box sets, so I got ten, and I think after a month of using them only three still work, they are a very loose fit in my gun, KWA KM4, but they do feed perfect when they are not jamming. So overall very disappointed in these magazines, I wish I could've returned them.
And I wouldn't not recommend these to a friend, let alone someone I hate.
Feed great when not jamming
Very very durable
Terrible purchase, wish I would've done more research before buying.
