So I bought a handful of the hexmags for the ar15. Left a bunch of them loaded as I do my milspec aluminum mags and my Pmags. Go to rearrange a few things and found that every single one I left loaded had cracked at the seam and now they don't hold bubblegum. Kind of upset and I reached out to hexmag to see what they will do or say. Anyone else have this type of thing happen? Any use for these mags now or am I SOL unless hexmag decides to replace?
