FAB Defense magazine problem

[u/Over_Independent8887]

I have those magazines but for some reason something is wrong and they just don’t work in any 5.56 rifle I tried.

The bolt just gets stuck on lips somehow and doesn’t even touch the round to feed.

I would appreciate if anyone could share their experience. I am sure they are good brand and should work :)

Thanks !

I see :/ thanks. I have great experience with FAB stocks so thought mags will be as good
