M&P 45 14 round mag sleeve material

[fullmann]

Can anyone with the FDE extended 45 mags tell me what the material of the sleeve is?

Got a line on some FDE at a stupid cheap price, and I want to see if they are a plastic that can be dyed black, or more of a rubber that will be FDE forever

Thanks in advance

I ordered the 6 pack of FDE for $60 from Botach.

Will report back if they can be dyed

Hard plastic, and I haven't yet figured out how to get one off the magazine.
