M15 Magazine

[PK90]

I posed this question on AR15.com and was hoping to get more of a response.

Are the Armalite M15 post-ban 10 round magazines aluminum or steel?

Do they have the restricting deep channel sides or a interior base blocker?

The catalog lists the mags as aluminum, but my Dealer Pricing List states the EX0072 as being steel. Which is correct?

They are steal. With the deep channel sides. I have one that came wth my rifle but I have never used it. It is about the same size as a 20 round mag is. I think it is made by triple k or some after markey company, it says armalite no where on it. For that matter it does not have anything printed on it. POS. Hope this helps.
