One of the guys on my team uses Lancer mags with great results. This week, I noticed that one of his mags had a problem with the base pad coming partially off. The mag still works fine, but I wonder if other people have had similar problems.
The mags were carried in open top mag shingles, and have seen about 6 months of daily use and abuse in Iraq. This is the only mag out of 14 that has this issue.
Besides this issue, the mags are holding up well to over here.
