Shawn has long ranted and called BDM products junk. Mine worked, so I was happy with them.
But I hadn’t used my BDM .22 mags for a while. I went to pull them out of storage and I found they all had cracked. One failed catastrophically, and all the other have bad cracks propagating through them.
I paid $35 each for these. I never abused them. What a bad deal.
Put me firmly in the “Don’t buy Black Dog Machine magazines” camp.
