G36 Mag Problem
 

I bought a pair of MAG brand 100 round mid caps, 1 is fine but the others spring became really weak.
It will shoot all the way but it would leave about 7 bbs in the magazine
has anyone else had this problem?
used it 6 games and I never had bbs sitting inside them over night or anything like that.

I have a TM G36C if that helps anyone

What do you expect for $10 mags. You can try twisting open the cap at the bottom take out the spring (watch out for a white tube that may shoot out) and give it a stretch.

(btw I have the MAG Sig ones)
