I have tried various different Hi Cap mags for my gun Dboys,ASG,JG,etc
And I have always found the mag that came with the gun gave absolutely fantastic feeding and looked nicer with the 5.56 trades on the side. So I decided to go out and get myself another of the 450 round G&G Hicaps as seen here-

I know it's a tad bit more expensive than the chinese brands but the quality and the effortless feeding is just so worth it in the middle of a skirmish. Seriously. I highly recommend trying these mags for you STANAG (M4/M16 mags) gun. If they work as well for you as they do for me, you will never go back! I just wanted to share with people who aren't sure what mags to get. If you like Hi Caps , 450 is not too shabby at all. Thanks for reading and if you have a different or similar opinion, please share it with me.
Thanks , Drew
