I recently purchased one of these with hopes of making my reload 20 rds. I got it to work 100% on one range outing but every other time it has constant FTF. I of course used the + power spring that came with the kit. Does anyone have any experience with these working well? Would love to somehow fix or improve this. These results are with Underwood. I might try a mid power Remington box next.
I run five of these in my MG20 CCU and they feed 100%
Try turning the end of your Mag Spring up a little, like seen here:

Bottom Spring is Stock and the top one is after the fix:

I only have one, but it works well with Corbon and lower power stuff. I've never tried it with Underwood.
Thx guys, I will try that adjustment if I get anymore failures.
