Using this with 2 G&G Metal High Caps and Umarex G&G Mp5 A5. WORKS GREAT.
I would have made it 5 stars except I had to remove rubber pieces so the mags would actually fit.
Incredibly useful and makes reloading a breeze.
Very sturdy, My magazines haven't moved at all.
Not too heavy.
Had to remove 2 of the rubber pieces from the inside of clamp to make the Mags fit. Came out extremely easily using a screw driver and/or knife.
**Note - The pieces I removed are only there to protect the mags from getting scratched.
