Yes I have the exact same problem as described above. I am not sure if it is because the follower on the lar mag sucks or if the bolt catch tab that the follower engages is too small.
I will try to fill the dented follower with some jb weld or epoxy to see if it strengthens it
I also noticed that the lar follower tilts and doesnt engage the bolt catch
I have not used any other mags, so don't know if the problem is isolated to just lar mags or if it happens with all mags
Im also having this issue!! ive ordered new magazines in hopes of curing the issue with a higher quality follower, but i must say im not really impressed by the expense, cost, and waist of time and i would like a bit more help from the supplier, in all really kind of a big let down so far
