Read the "fine print"
Note: Magpul has recently released the Gen 3 M3 Magazine. The magazines listed on this page are Gen 2 PMAGs with the dust covers. The M3 magazines will have a different part number when we receive them.
They are merely pricing them out of stock. Meaning intentionally raising the price so nobody will buy them and they can stock the newer/later/greater model or whatever. It's common practice in businesses actually. Some of my employers' vendors do the same thing with certain components and I know M&A Parts does it too.
Is Ruger replacing the BX-25 magazine with a new model too?
