I'll be assembling my lower in the next few days, will post update in this thread if the Magpul extended mag release does indeed fit and function in the MS lower.
EDIT:
The Magpul release DOES fit and function, it is very close to the top of the pocket but seems to function fine.

Stand and deliver - freedom is not free, and never has been. Resist the Reset!
I have my lower and it looks fantastic!
Thanks ATRS!!!
