These mags look and feel great. I would like to note that they are a little gray in color instead of black. Not that this is a negative but something to point out.
Clear top to prevent over filling
Didnít work very well in my KWA M4S or JG 416.
The mag fits very tight in the KWA where you have to give it a lil smack to make sure itís all the way in, and requires a slight pull from the mag when you push the mag release. Had some dry fire (prob b/c it wasnít smacked in all the way) and had a few dribbles when first loaded. Once seated correctly it fired very nice.
The JG on the other hand went in very nice and came out with just a push of the mag release. It did have a lot of dry fire and i ended up giving up trying to empty the mag. :(
I wouldnít hold this against the mag, it seems to be made with quality parts... It just didnít work on my guns... :(
