fxo black plastic bottom magazines

[HerbZ]

I think Lugerdoc has it right! I can push the pin out on the original (upper photo) magazine with no trouble at all. I just did it with a 1.5mm easier than pushing a toothpick into whipped butter.

Here's a photo of what this magazine bottom looks like on the inside. It has a raised mark of some sort molded into it. Looks at first like a dollar sign, but under a 10x triplet looks like a capital I inside a larger capital S.

Looks upside down in the preview of this post. (I'm doing this all at our kitchen table with my phone while it's plugged in recharging.)
