9mm AR15 question

[loadnplenty]

I purchased a NIB Palmetto 9mm lower that takes glocks mags for steal of a seal.
Since Palmetto doesn't have any 9mm uppers complete in stock they are a no go.

Will I have to find an upper that is Glock mag comparable or does it even matter?

The Glock mag refers to the BCG cut as it a little different from Colt pattern. Any 9mm upper with Glock BCG should work.

Ok thanks. Now to locate one that's not $200+
