Hello, I'm going to get right to the point. I ordered a g&G combat machine. I bought a Pmag midcap 75 rds. It feeds great. I got some mag 100 rd brand mags and it only feeds about the first 20 or the first 50 if i shoot it upside down. If anyone has any tips or tricks on how to make it feed better (I tried silicone). Thank you all for the help
Likely it was a little dirty, or you used a lower quality bb which got jammed in there. Either way adding silicone is just a good way to get it to gunk up again since it attracts more dirt. If you run a swab down it, make sure you follow it with multiple clean, dry swabs. Also remember the swabs should be something that isn't going to leave behind fibers like paper towel or toilet paper will.
